I’ll try to post a longer answer later but Rust is really for systems programming and its choices follow from that. I liked this article:

chrisdone.com/posts/rust/

I think one thing to mention is that Rust is highly specific in what it does. In most of the examples you mentioned, string types, tokio::main, you can essentially just say that rust is more explicit. When initializing an integer variable in C using int, it’s not specified what use the integer is or whether it’s signed or not. i32, uint16_t you can see how it’s specified. Using tokio::main before your main function just specifies that you’re using the tokio asynchronous executor for your async code. In the case of string types, they all have different implementations which just help with being specific.

The reason I like Rust is because I know what’s happening when I read it. Did I have to read the whole async book to understand how the tokio::main stuff works? Yes. But now I understand exactly how it works. The problem I have with using Javascript is that it doesn’t have that high amount of explicitness(is that a word?). At the end of the day, if you’re using it for a personal project or you’re arguing for language supremacy, it really just comes down to personal preference.

rust is a systems/low overhead programming language. really not much of a point comparing js/ts and rust, since js is much higher level. you should be comparing it with c, c++, zig, maybe nim, etc

you also imply it’s pointless to have a language geared towards performance because computers are better now, but 1) programs run on more than just personal computers and you wouldn’t run js in an embedded system and 2) just because your computer can put up with poor performance and resource waste doesn’t mean that it’s sensible to do so (hello electron)

also, rust does more than just cosmetic improvements. it adds a layer of statically guaranteed memory safety that no other commercially viable programming language that i know of has. even if its syntax looked like ancient eldritch runes, it would still be an attractive language. the fact that it manages to do more than other languages while still having a decent syntax is amazing

you can dislike rust if you want that’s fine but you don’t need to try to shit on it just bc it’s not your cup of tea

A reason to not distribute a library as a binary is for cross platform support, this allows a library to technically be compiled and used in some other platform; with that said, there are assumptions about having the same system calls (or that the library only handles abstract things that don’t hook into a specific architecture), with that said, making cargo smarter and adding in the option to bundle some prebuilt libraries to be pulled for compatible platforms could speed some compile time (at the likely cost of build size, etc).

Distributing a library as source isn’t some weird rust paradigm, take BOOST for example, which is a large library for C++, and is usually distributed as source (but Linux distros may bundle prebuilt binaries; it is generally intended that you will compile it and use it as a shared library), actually a lot of compiled languages distribute their libraries as source, it also allows you to read their source if you need to see exactly how they’re doing something). I don’t believe there is anything preventing someone from using shared libraries in rust, although they do seem to be less common. Another reason to distribute a library as source is for licensing.

The unstable versioning… Ya, that is definitely annoying, and likely tied to the limited resources available for sustainment for various projects. With that said, compared to C/C++ many of these libraries are something that one might role their own or use in house libraries. Now for Tokio… You don’t have to use it for async, although you probably will want to (see: blog.poespas.me/…/rust-async-std-and-tokio-compar…), I do wish there was a nice way to depend on a library and substitute some of its dependencies (aka Tokio); with that said, part of the cargo idea is that you don’t view these libraries as part of your source code for review (although, auditors would likely disagree, so acrediting with the inclusion of many in accredited libraries would probably not be fun)

Frankly, all of your points sound quite ignorant. Syntax is literally just a matter of getting used to it. Comparing HashMap ergonomics doesn’t make sense, you should rather compare to struct construction. There are many good reasons for different string types and number types. There are good reasons not to bake in async. Rust documentation is in the code for a very good reason and it’s actually really nice to read docs like that (obviously read it on docs.rs, not in the code itself).

I could go on but there are answers to all of your specific qualms if you just bothered to look for yourself.

Rust syntax is badly designed compared to most other languages I used

It really isn’t badly designed. Yeah there are more symbols than you are used to from JS/Typescript world. But more symbols does not mean bad syntax. It makes things more explicit which IMO makes things easier to read and understand what is going on. Rather than all the implicit behavior in JS/TS.

Let’s take a look at hashmaps vs json

What is the point of this? Lets compare two different things to prove no point! Look I can do it to:

let person = Person {
  name: "joe".to_string(),
  age: 23
}

const scores = new Map();

scores.set('Name', Joe);
scores.set('Age', 23);

Why would you construct a map like this? That is not what maps are for in either JS or rust. But either way all these examples are easy to read and can tell what they are doing even if you have not coded the language before. Now you do need more of an understanding of rust code to read some rust code but not these examples given.

Every single library in rust is half-baked.

That is just hyperbole. Many rust libraries are very mature now. Not having a website is not a sign of maturity and the docs for axum are very good in rust docs site. If you really want a webserver with a website then you have actix-web. Many rust projects do have sites like this or even books on how to use them. And if you look at the JS ecosystem, how many libraries do you use there that have nothing more then a readme on their github page? IMO I tend to find far worst documentation for JS libraries then I do for rust ones - if you look beyond the big things like react.

No GUI framework is as stable as something like Qt or GTK

This is true of basically all languages but C/C++ and maybe JS. Most languages just lean on these for good UIs, but there is a lot of effort ATM in getting nicer GUI support in native rust. It will come with time but a GUI library is a complex thing to make.

literally every rust project has like 1 dev maintaining it in his free time and has “expect breaking changes” in the readme

This is just more untrue hyperbole.

Apparently everyone loves dealing with hours and hours of debugging basic problems because it makes you a better programmer, or there’s some information I’m just missing.

One of the things I love about rust is I don’t need to spend hours and hours debugging basic problems because the language is explicit and makes me think better about things upfront. Rather then spending hours wondering why something is producing weird output at runtime because something somewhere else got a “1” instead of a 1. It takes a bit more effort to get something to compile, but I find vastly fewer surprises at runtime then I do in other languages. And it is those runtime bugs that take the most amount of time to solve.

When you’re running a company you don’t have time to mess around with syntax quirks, you need thinks done, stable and out the door

You also don’t want things to break in production and have to spend hours and hours debugging some weird edge case.

Cargo being an all-in-one tool is actually one of my favorite things about the rust ecosystem. It’s many things, and it does it all seamlessly.

Regarding comparing to C or C++, how can you argue either is designed better? C, while standing the test of time, predates so many modern programming concepts or standards and writing C code is extremely error prone. C++ improves on many of C’s shortfalls, but it wasn’t designed. It’s the result of different things being loosely bolted on to C over the course of 30 years. And it’s still error prone, for example while there are smart pointers and other types that can make writing memory safe code possible, they’re not default and they aren’t always fully supported in the standard library, let alone anything else.

Try Scala. It has all the functional goodness, all the OOP goodness, all the imperative goodness, clean syntax like python or like typescript, really well thought out libraries like ZIO, Akka, Tapir, Caliban and access to all Java libraries. Very mature runtime with best-in-class high performance concurrent GC and a green thread implementation that can handle 10s of millions of concurrent operations.

Cargo is doing too many things at once. It’s a build system but also a package manager but also manages dependencies? Idk what to even call it.

Somewhat agreed, but it’s a very difficult problem to solve. No language has yet come up with the perfect build tool. JS is on what, like the 12th build tool in as many years now? Some serious throwing stones in glass houses vibes here.

Syntax is very confusing for no reason. You can’t just look at rust code and immediately know what it does.

Strongly disagree on this point. Those extra glyphs in Rust are not just cosmetic, each one means something very specific and conveys very important information.

Having to pollute your code &, ? and .clone() everywhere to deal with ownership

You don’t “deal with” ownership, it’s an incredibly powerful tool you use. This just sounds like you haven’t really understood what the borrow checker is actually doing and the hundreds of problems it solves for you. I can not count how many times now I’ve been working in another language and had the thought “I could solve this with the borrow checker”

Js is way more readable.

JS is not more readable, JS is just far less detailed. It omits a vast swath of information such that you have almost no idea what it’s actually doing. It feels easier to you because you don’t care about any of the details, but those details become vitally important when things stop working and you’re trying to figure out why. This sounds to me like you’ve never had to write any actually complicated code. If all you’re trying to do is chain together a series of HTTP calls and maybe parse a tiny bit of JSON, yeah, Rust is like using a nuke to kill an ant.

Similarly, Async code starts to look really ugly and overengineered in rust.

A little bit, but mostly because doing async right is really complicated. Once again no language has a really great solution to this problem yet, they all involve tradeoffs.

Multiple string types like &str, String, str, instead of just one “str” function.

Once again it seems you don’t really understand the difference between owned and borrowed values or stack vs. heap allocation and why it matters. Really there’s only one type of String which is String, the others are just different ways of borrowing a String (with different tradeoffs).

i32 i64 i8 f8 f16 f32 instead of a single unified “number” type like in typescript. Even in C you can just write “int” and be done with it

If all you want is a “int” you can just use i64 for everything and “be done with it” as you say, you’ll just be adding a ton of wasted memory and needless overhead for no good reason. Seems like you just don’t like strong typing. I’m surprised you even bother with TypeScript instead of just using JavaScript.

Having to use #[tokio:main] to make the main function async (which should just be inbuilt functionality, btw tokio adds insane bloat to your program) yet you literally can’t write code without it.

You absolutely can write code without using #[tokio:main], you can even use tokio without that, it just saves you having to write a bunch of boilerplate to initialize tokios executer and pass your async functions to it. You can even use async functions without tokio, you just need to provide your own executor. Async in Rust is still pretty new and some of the rough edges are still being worked out, it will get smoother, but honestly the things you’re complaining about aren’t even the annoying parts about it.

Speaking of bloat, a basic get request in a low level language shouldn’t be 32mb, it’s around 16kb with C and libcurl, despite the C program being more lines of code. Why is it so bloated? This makes using rust for serious embedded systems unfeasible and C a much better option.

I have no idea what you’re doing to generate code sizes like that, but I guarantee you could get a significantly smaller program in Rust that does exactly what the C code is doing. As for embedded this is patently false. I personally use Rust regularly on embedded devices that don’t even have 32mb of RAM on them.

With cargo you literally have to compile everything instead of them shipping proper binaries. Why???

This isn’t a cargo thing, this is a Rust compiler thing. The Rust ABI hasn’t been standardized which means currently there’s no guarantee that Rust code compiled by one version of the compiler can successfully link against code compiled by a different versio

Then use C or C++ if you really need performance.

And that’s where I stopped. I’m a real working programmer who’s done tons of work in C++, so I know firsthand that it absolutely sucks compared to Rust. Go back to Typescript if you hate Rust so much.

@cybergazer
> Syntax is very confusing for no reason.

This comment alone (followed by your examples) tells me you don't understand what problems Rust is trying to solve.

You have to keep in mind, when you write JavaScript, there’s an entire runtime written in C++ to run it under the hood, with some crazy optimizations to make it reasonably performant. What type of languages do you use to write that runtime? A systems programming language like Rust and C++.

You don’t have to use Rust if you don’t like it. Not everything must be written in Rust. The whole pick a language also involves a lot of picking your tradeoffs. Picking a interpreted/JIT language for speed of development is a perfectly valid tradeoff, but not one you can universally make. Sometimes the performance cost becomes really expensive currency-wise, where you can save thousands of dollars on server costs by simply having a more efficient application that only needs a fraction of the hardware to run it. Even in JavaScript, a fair chunk of libraries you use end up calling to C++ native code because it would be too slow in pure JavaScript. Sometimes the tradeoff is pick the popular language so it’s easier to hire for cheaper.

Even at the dawn of time, most computers shipped with a variant of BASIC so people could write simple applications easily. But if you wanted to squeeze out every bit of power in your Apple II or C64, you sure did reach for assembly. Assembly sucks so we made C, then C++. Rust is still a language that’s made to eventually compile to assembly/binary and have the same performance as if you wrote it in assembly.

And low spec hardware still exists: the regular Pis have gotten pretty fast but if you run on an RP2040 then suddenly, you’re back in like 300MHz dual core land with pitiful amounts of memory, so you do need to write optimized and fast code for those.

Rust’s type system is actually really, really good. Most of the time, if it compiles it runs. It eliminates a ton of errors other than memory safety: the system is so powerful you can straight up make invalid state unrepresentable. You can’t forget to close a connection, you can’t pass the wrong data, you can’t forget to unlock a lock. It does a lot more to enforce correctness of a program well beyond memory safety.

Cargo is doing too many things at once. It’s a build system but also a package manager but also manages dependencies? Idk what to even call it.

Coming from Java where you have no standard tool and two current defacto standards (Maven and Gradle) which do similar things in a less clean or standardised way, I think Cargo is one of the least contentious parts of the Rust experience.

Supposively bad typescript

Correct. Bad Typescript. You haven’t provided any of the type information to make this a TypeScript construct (this is just JavaScript)

It should be something like…

interface Person {
    name: string,
    age: number,
}

const person: Person = {
  name: "joe",
  age: 23,
}

And the Rust equivalent being something like

struct Person {
    name: String,
    age: u8,
}

let person = Person {
    name: "joe".to_string(),
    age: 23,
};

i32 i64 i8 f8 f16 f32 instead of a single unified “number” type like in typescript.

Those all have different sizes and capabilities. The lack of these requires the JS JIT compiler to try and guess (and deoptimise when it’s wrong).

Even in C you can just write “int” and be done with it so it’s not really a “low level” issue.

No, you can’t - en.wikipedia.org/wiki/C_data_types

• Similarly, Async code starts to look really ugly and overengineered in rust.
• Having to use #[tokio:main] to make the main function async (which should just be inbuilt functionality, btw tokio adds insane bloat to your program) yet you literally can’t write code without it. Also what’s the point of making the main function async other than 3rd party libraries requiring it?

I agree the Rust Async experience feels a little messy, and the lack of an opinionated default makes even the foothills a steeper climb than we might hope. However given all that it’s trying to achieve (in terms of Rust drives for efficiency and safety) I don’t have any better ideas right now.

Speaking of bloat, a basic get request in a low level language shouldn’t be 32mb, it’s around 16kb with C and libcurl, despite the C program being more lines of code. Why is it so bloated? This makes using rust for serious embedded systems unfeasible and C a much better option.

I don’t know how you’re getting to 32MB. A release build of the most basic form of a get request is not that bad.

A simple chatgpt generated one app to get the content of an HTTPS URL, using reqwest and tokio is 4MB. I expect this can be reduced with options.

However yes, the default Rust build (with all of the panic machinery and more) is bigger than C. But Rust doesn’t have to be the best choice for every niche, to be an excellent choice for several. With that reasoning your return to TypeScript is equally flawed.

Another major issue I’ve encountered is libraries in Rust, or lack thereof. Every single library in rust is half-baked.

Coming from Java, Rust’s young ecosystem is definitely noticeable. It’s taking a while for it to grow, to mature, and for clearly dominant frameworks to emerge for various problem-spaces.

Java, like Rust, is not opinionated about the frameworks, but the size and age of the community means that clearly dominating frameworks emerge with huge contributor bases - Rust just isn’t quite there yet.

As for “memory safety”, it’s

(Wow, 14 posts in 2 hours on Lemmy… The old wisdom that the best way to start a discussion is to loudly complain about something rings true :P)

Cargo is doing too many things at once. It’s a build system but also a package manager but also manages dependencies? Idk what to even call it.

It’s still a build system; most (good) build systems also manage downloading and resolving dependencies. Having them all as part of the same tool makes everything slot together nicely.

Syntax is very confusing for no reason.

It’s not no reason; dealing with ownership is a complicated problem. It’s just that most languages tend to hide it and let the programmer tangle themselves in knots.

You keep talking about it being obvious what the code does but… Using :: over . helps clarify, at the call site, that you are using a “static” function rather than having to make the programmer look up the definition of the lhs.

Js is way more readable.

Pop quiz: Is this a copy or a reference?

let a = b;

You can just look at it and immediately know what the code is doing even if you’ve never coded before.

You can’t really… The JSON map object syntax isn’t actually intuitive to non-programmers. I’d argue that the rust version is more intuitive, since they can probably make a good guess based on the word “insert”.

Multiple string types like &str, String, str, instead of just one “str” function

These are distinct types with distinct meanings. JS and TS sacrifice some performance to make them seem like the same type, which may or may not be justified in your project.

i32 i64 i8 f8 f16 f32 instead of a single unified “number” type like in typescript.

JavaScript has three number types, ints, floats and BigInts. The former two are both called “number”.

Even in C you can just write “int” and be done with it so it’s not really a “low level” issue.

No you can’t. int is different sizes on different platforms. (EDIT: I was thinking about long. If you need more than 32 bits (which you do to store a pointer), that’s where the problem lies)

yet you literally can’t write code without [tokio].

I’ve never actually used Tokio. :D

Why is it so bloated?

Are you compiling at the same optimisation level, stripping debug info and statically linking libcurl in both cases?

Another major issue I’ve encountered is libraries in Rust, or lack thereof.

This is a big problem, I agree. Though to be fair, I’ve also encountered it with both NPM and PIP. Perhaps worse so there, because the compiler isn’t backwards compatible.

They’re invulnerable to memory issues unless you write infinite while loop and suitable for 99% of applications.

No they aren’t~ It’s easy to write code that hitches every few seconds (which kills games). And you also overlook the fact that a garbage collector is, quite frankly, a miracle of optimising compilers. I remember back in university being warned to remove the “next” pointer of graph nodes because otherwise memory would leak.

Then use C or C++ if you really need performance. Both of them are way better designed than Rust.

I develop professionally in C and C++. No they aren’t. At all. C and C++ are so loaded with footguns it’s a surprise people can get anything done in them without triggering UB.

Also, any program you write should be extensively tested before release

True. But nobody does that. And even if they did… Why not use a language that makes testing easier and faster?

you’d catch those memory errors if you aren’t being lazy

Not in any sufficiently large codebase.

that’s enough for the entire programming space to rank it year after year the greatest language

If you find that everyone in the world except you seems to be involved in some elaborate conspiracy, please check your reasoning.

And the thing is, that’s fine, the issue I have is people lying and saying Rust is a drop in replacement for js

Ehh… I don’t think it is. I think people interested in stepping up their programming game should give it a go, but branding it

I get the sense that you might appreciate golang.

Your LLM of choice needs better training.

… the issue I have is people lying and saying Rust is a drop in replacement for js

I am genuinely curious whether you’ve actually seen this claim before, or if you badly misunderstood or are simply exaggerating a claim about Rust being a good language for web servers, or if you simply made this up as a straw-man. I can’t imagine anyone who knows what they’re talking about using those words I that order.

I would very much like to address some of these points, since I don’t think you are making a good argument here.

I shall preface this by saying that comparing Rust to TypeScript is a bad idea. They are meant for fundamentally different things and you should not regard Rust as a TypeScript replacement. I will do my best to show why Rust took the paths it did whilst being as brief as possible, but if TypeScript is your measuring stick, you should stick to it.

First of all, cargo does a lot of stuff. This is true, but you are comparing Rust to TypeScript here, and therefore you should compare cargo to npm, npm is the same thing. It does everything all at once, and everyone loves it. Cargo doing everything it does is meant to be a convenient way to interact with Rust projects. That being said, if you don’t like Cargo, you can use rustc directly. You can compile Rust code much the same way you would C/C++, with a Makefile.

Multiple string types: As compared to TypeScript, this would seem like an unnecessary complication, but let’s compare it to C++ for a second. In C++ you have two string types as well, namely const char * and std::string. These are ‘basically’ the same as &str and String respectively. It comes down to whether or not you want your string to be heap allocated or not. Allocation is not something you get any control over in TypeScript and for that reason it is possible to have a single unified string type. Also, TypeScript hides the internal representation of strings from you, which is convenient, but can be a real pain in the butt if you’re trying to do low-level manipulations.

I would agree that Rust’s syntax can be quite terse, but this is due in part to it being a strongly typed language, unlike TypeScript, which is very weakly typed and can therefore simplify a lot of things.

Async code looks ugly in rust. Yeah, it does. Mostly because it’s not doing the same thing that it would be in TypeScript. TypeScript async code and Rust async code are fundamentally different. If you have a look at async code in modern C++ you will see a lot of the same complexity as you do in Rust, since it’s more closely related to what Rust does.

You say that rust has many different integer types, yet in C you can ‘just write int and be done with it’. This is patently false. Here is a catalog of Rust integer types and their C/C++ equivalents:

• i8 -> char
• u8 -> unsigned char
• i16 -> short
• u16 -> unsigned short
• i32 -> int (This is the only one you would get if you just write int.)
• u32 -> unsigned int
• i64 -> long long
• u64 -> unsigned long long

In TypeScript you have just number, that’s true, but it’s a managed language. Again, this hides the complexity from you, but it comes at a steep cost. If you actually want to do low-level manipulations, you have to drop down to something like a Uint32Array type, which is exactly equivalent to [u32] in Rust.

Having to use #[tokio::main] to make an async main. This makes me think you don’t understand how async code works. The reason you can just write async code in TypeScript is because there is a runtime. Your code doesn’t just run. You need a browser or a Node.JS server or something similar. That is what tokio is (kind of). This also addresses the bloat argument for tokio. Rust does not have a runtime, and therefore when you want to write async code, you need to add one. In TypeScript land, you just get the runtime whether you want it or not.

As for GET requests being 32MB, I don’t understand what you mean here. The request itself will never be that large. If you are complaining about the binary size, though, you are likely compiling in debug mode. Switch to release mode and add -C opt-level=3 to the compiler flags and you’ll get a binary that’s way smaller.

About the libraries, Rust is a young language. Libraries can be hard to find for specific purposes, but that will change over time. Axum doesn’t have a home page, btw, because the docs.rs page is more than good enough.

Memory safety is not a buzzword. In mission-critical software (which you would never write in TypeScript, because it’s buggy as all hell), memory safety is something you have to have. If you are using C/C++, your memory safety is ‘trust me bro’. ‘Just use a garbage collector’ is not an argument. When people want memory safety, it’s exactly because they don’t want a garbage collector. I won’t go into the specific details, but you are pigeon-holing Rust in with languages like TypeScript and Java, which are designe

Ok, I’m going to just assume this isn’t a troll.

Cargo is doing too many things at once. It’s a build system but also a package manager but also manages dependencies? Idk what to even call it.

I dont even understand your issue? It’s like npm or deno which can run your code, manage your dependencies, etc. How can a JS/TS dev possibly not understand this?

Syntax is very confusing for no reason. You can’t just look at rust code and immediately know what it does. Having to pollute your code &, ? and .clone() everywhere to deal with ownership, using :: to refer to static methods instead of a “static” keyword. Rust syntax is badly designed compared to most other languages I used. In a massive codebase with tons of functions and moving parts this is unreadable.

I dislike ? because I think you should be handling errors as they come instead of sending them up the stack. I also like the explicit .clone() but if you dont want to use it, you can also add Copy to your derive’s and this will make it happen automatically. module::function() generally pollutes code much less then static module.function() or static function() doesn’t it?

Let’s take a look at hashmaps vs json

I hate all of this code, why arent you using struct’s here? In rust its: struct Person {name String, age i32} and in typescript its type Person = {name: string age: number}

Similarly, Async code starts to look really ugly and overengineered in rust.

Sure

Multiple string types like &str, String, str, instead of just one “str” function

I know of &str and String, i’ve never heard of str though so you probably dont need it. &str is a string slice, aka a borrowed String. I generally say you shouldnt be using &str because generally if you get a lifetime error from using it, its because you’re doing it wrong, just use String while you’re learning the only real difference is that String is more verbose then “”

i32 i64 i8 f8 f16 f32 instead of a single unified “number” type like in typescript. Even in C you can just write “int” and be done with it so it’s not really a “low level” issue.

“int” from C is i32, these are int’s and float’s of various bit sizes. i32 = int 32bit, i62 = int 64 bit, f32 = float 32, u32 = unsigned (only positive) int32. but you dont usually need to specify this, rust has type inference. Also speaking of C, what about double, long, short, long long, unsigned long long, unsigned short…

Having to use #[tokio:main] to make the main function async (which should just be inbuilt functionality, btw tokio adds insane bloat to your program) yet you literally can’t write code without it. Also what’s the point of making the main function async other than 3rd party libraries requiring it?

I kind of agree? When async was initially designed it was done as a stackless minimal thing where we could build our own runners (like tokio) but no one really builds their own runners, they just use tokio.

Speaking of bloat, a basic get request in a low level language shouldn’t be 32mb, it’s around 16kb with C and libcurl, despite the C program being more lines of code. Why is it so bloated? This makes using rust for serious embedded systems unfeasible and C a much better option.

I don’t believe you, show me this project. As a personal project I have made a monolithic web server, that handles api calls, webpage calls etc, it uses axum, tokio and serde and when I run cargo build --release it compiles down to a 1.9mb binary. The only way I can see this happening is if you’re not using a release build, which is a concept you should understand as a JS dev.

With cargo you literally have to compile everything instead of them shipping proper binaries. Why??? This is just a way to fry your cpu and makes larger libraries impossible to write. It should be on the part of the maintainer to build the package beforehand and add the binary. Note that i don’t mean dependencies, I mean scripts with cargo install. There is no reason a script shouldn’t be compiled beforehand.

This argument has happened a few times that I know of. This is done for security purposes. If someone ships a binary blob you have to trust it to run, as a community, it was decided that we shouldnt do this.

Another major issue I’ve encountered is libraries in Rust, or lack thereof. Every single library in rust is half-baked.

I kinda also agree with this one, a lot of rust libraries are still in 0.x, I wouldnt call them a

If your primary exposure to programming is only typescript or JavaScript maybe you shouldn’t be jumping straight into something like rust. JS is a high level language and rust is aimed at the lower levels where things can’t be as automatic. There are many languages out there like C#, Kotlin and Swift that will help you get used to the idea of strong types and immutability.

That example is so insanely readable lol

Absolutely standard looking code for many languages.

Oh but in rust you learn more about computers/low level concepts, you’re just not good at coding”

Who cares? Coding is a tool to get shit done and I think devs forget this way too often, like if one works easier than the other why does learning lower level stuff matter?

This is pure junior energy. Or trolling, I honestly can’t tell.

Even though most of the specifics you point to are wrong, it’s a good point overall:

Rust, being #1, should be better than all other languages. The fact that it’s just decent makes it seem overhyped, and all the downvotes on haters make it look like a cult.

Back when it was small, the cult-like following was OK. But now that the language is becoming more mainstream I think the Rust evangelizers need to tone it down a bit or they risk pushing people away.

On your point, TypeScript is a decent language too. There can be two good things.

Having to use #[tokio:main] to make the main function async (which should just be inbuilt functionality, btw tokio adds insane bloat to your program) yet you literally can’t write code without it. Also what’s the point of making the main function async other than 3rd party libraries requiring it?

You’re kidding, right? You do actually understand that languages that aren’t JavaScript don’t have built in async runtimes and they need to be provided by a library, right? You’re not actually writing a post about how much the programming language you have two days experience in made different design decisions and is therefore good at different things than the programming language you have five years experience in and therefore it sucks, right?

There are plenty of slimmer async runtimes for Rust. Pollster comes to mind, although it doesn’t provide any I/O functionality. (That’s where the “bloat” that’s in Tokio comes from – it’s providing functionality the Javascript runtime has built in. You see, Rust, unlike Typescript and Java that have compilers that emit source code for an interpreter, is actually a compiled language, and Rust programs compile to self-contained executables that don’t need any external dependencies to run. If you included the size of the node binary in your Javascript app, Rust would win the filesize war no contest.)

As for “performance doesn’t matter” – I’d like to tell you a personal story about a Rust program I’m working on. There’s an imageboard I’m a fan of, and it runs some booru-like software, meaning when you upload an image you give it a few dozen tags, and then people can search for images by their tags. The tag search functionality on the website I thought was missing a few features, so I downloaded a copy of the entire post database on that site (including URLs and tag lists of every post) and wrote my own search algorithm in Rust. I wrote a function that accepts a search query and a list of tags and returns a boolean, and searching the posts was as simple as vec_of_posts.iter().filter(|post| matches(search_query, post)).collect(). I then downloaded the rayon crate, and, with a sngle line change to vec_of_posts.par_iter().filter(|post matches(search_query, post).collect(), I was running the search in parallel on all CPU cores. Running a full search of all four million posts takes about 50 milliseconds on my laptop, or 3 seconds running the search locally on an Android phone. Try that in an interpreted language.

(So help me God, if you respond to that last point by saying “cloud computing”, I am going to shoot you in the head.)

Welcome to compiled systems programming languages? What’d you expect?

All your arguments can be applied when comparing ts to js. You can just use the succinct and readable js. Why waste time dealing with this type is implicitly any?

Get things done with js and chill.
