Damn, after getting more comfortable with the idea of calling opencl code from either python or rust, or c code from python, wrangling c types in all cases, I've been meaning to get to calling rust from python, did not realise it can be this easy (especially for end users too), this might be exactly what I wanted, you've saved me some research :). I kinda like c, but I do find myself missing generics, traits and maybe sum types and pattern matching, not super fussed about automatically checked safety, you still end up having to think about what needs to be accessed from where (and apart from rust-gpu, we still don't really have this for GPGPU), but hey, automating some of that with the compiler can't be a bad thing. All in all, looking forward to using rust for more stuff, apart from when I would find a repl more convenient (data analysis and plotting). Knowing what functions can and can't fail and where you might have to think about nulls is also pretty cool.

I was actually incorrect about this! I added a correction in the pinned comment, but essentially you can use u64 or u128 for this too. Of course, there will potentially be memory constraints, especially for larger Fibonacci numbers, but they can be easily overcome using a better algorithm

True! C is harder to get started with from a tooling perspective though. Which compiler do I use? What formatter? etc. etc. Rust doesn't give you a choice, and all the tooling is in a single CLI app, which makes it really easy to start. Yes, the language is a bit more difficult, but it's much easier to write safer code in Rust than C

@IsaacHarrisHolt

9 ай бұрын

Good question! Mostly because I'm not familiar with it, but also Rust and Python is a very popular combination at the moment and I couldn't find many good videos on the topic, so I decided to fill the gap.

I tried to create and return a simple list containing 1 million integers in range with the following: #[pyfunction] fn create_integer_list(n: usize) -> PyResult { let mut result = Vec::new(); for i in 0..n { result.push(i); } Ok(result) } when I compile it in RustRover it runs in 8 ms. However, when I create it in maturin as per your instructions, it takes roughly 110 ms to run. Any idea what's causing it? I ran maturin develop --release

@IsaacHarrisHolt

It's very possibly the interaction with Python. When you say you're compiling it in RustRover, are you simply compiling it as a Rust binary or as a Python library?

@@IsaacHarrisHolt Sorry I was unclear, I meant that I ran the same code as above in RustRover which worked great, as opposed to when I ran that code through maturin. I have narrowed it down to the PyResult return of my function. It seems like returning a vec and "retrieving" a list in python is really slow. Gonna see if there is a way to return a list of values in a better way

What are you talking about? u64 and u128 are supported in 32 bit machines lol, the compiler fixes that for you. Please add this correction as that is highly misleading. That being said, it's very rare to build for a 32 bit architecture in 2023 if you're not in embedded, and there you have a whole lot of other things to worry about.

I wish there was anything similar for doing it with c++ and pybind

@IsaacHarrisHolt

9 ай бұрын

I'd not heard of pybind! It looks like a minimal version of Boost, but it would be nice if there was a build tool for it. Technically maturin and PyO3 are separate tools, so there wouldn't be anything preventing you from creating the equivalent for pybind11.

Let's not fall into syntax similarity trap. Rust is wonderful language, and I'd use it for other reasons than similarity of syntax. In fact popular modern languages such as Rust, Typescript, Scala, and typed Python share syntax with good old Pascal, which would be the first programming language that you would learn in my days (except basic). Personally, I have rewritten PoCs in Python in C++, and I didn't find it any difficult, actually I could achieve most of those rewrites by copy & paste of Python code, and then run some VI macros to add types, compile and all works! I don't think it is that simple with Rust.

@IsaacHarrisHolt

3 ай бұрын

You make very good points! I usually only mention the syntax similarity because it slightly reduces people's "fear" of Rust. Lots of folks hear that it's hard and then don't want to try it, so it's just another reason it might not be that scary. Naturally, it's not the most important thing when considering which language to use to extend Python. Honestly, I think the most important consideration is whether you even SHOULD be using a different language when there are so many things you can do to optimise Python code first.

I'm both a python (on job) and a rust (newbie and hobby) programmer. And before I start my criticism: Yes, pure python code will be slower than rust code most of the time. My issue is the abundance of oversimplified benchmarks on the internet like this one. Please stop doing those. New programmers will pick up those examples and will think these are mostly okay. Please, use real-world problems whenever possible and solve it with your best effort on both sides. Don't trust the results and don't jump on conclusions. Verify the results as good as you can and be as transparent as possible when publishing the results.

While I do typically agree with your approach, this video is aimed at people who can't really write any Rust, so I needed an example that would easily translate from Python to Rust without causing any confusion.

Wtf you are talking about, the tutorial does what video name says,... What real world problems , what oversimplified benchmark ? Benchmark is good, shows simply comparison of those 2 languages. What is Real World problem ?, in real world, like almost a year, I move data from frontend to backend, to database or file storage, read and open and refactor files,....

I feel like every language-plugger and C-hater in the world keeps forgetting that their favourite language runs on top of about 5 million lines of well-tested and functioning C code. It's no longer feasible to write any language at all without libbing out to C for most of its basic functionality (like opening files, accessing memory, listening to sockets, connecting to servers etc etc), simply because if you spend 2+ years getting the basics done, your language will get overtaken by something else.
