I followed a web guide to use Rust code from within a Python Dash web app. It blows my mind how many different ways there are to do things in programming. Makes it very difficult to learn.

Just breathe and focus on getting the product (and the next obvious step) done. You will figure it out. Discuss it with somebody from time to time. You will find mentor, and it will work out. Do not forget to focus on the goal of your code, and push for getting the result - the code doing the stuff you want - done. Keep the log, write stuff you learn along the way in a form which will help you to reproduce again it if you get lost. And good luck to you in your journey!

Difficult? Or just more time consuming. Learning assembly is difficult. Having multiple ways of doing one thing is just called having options.

I am slowly moving over to Rust from C++ since I have come to despise the package management in it. Cargo provides easy-to-use package management, which I love dearly. Now I can focus more on the actual logic than worrying about how to link up my whole code. However, sometimes I wish to access Rust's robustness and 'easy-to-use'-ness through C/C++. So, please, it'll be beneficial if you make a video on how to call Rust from C/C++ and vice versa. PS: I really love your videos. If possible, I would love to get in touch with you to discuss Rust's future prospects and how to improve myself in this language.

Really good content. Short and concise!

Your content has helped me learn rust tremendously well

Wow, I'm constantly diappointed you don't have a merch store or such, because I'm always binge-watching your wonderful content. I would love to see Rust integrated with Lua, as Lua is a wonderful language designed to be embedded into lower-level software environment like C/C++.

I love the channel and its definitely helping me fall in love with the language! Could you do a similar video to call rust from Node?

Great content, some how we need another version too: "Calling Python from Rust"

Really great content. As I recall, other similar cross language integrations often lose a good bit of performance when jumping between the hidden glue code that allows them to be used together (such as Java with C++). Best practice is to make course-grained functions in the lower-level language (such as rust in this case). This way you do not waste too much time going back and forth across languages before calling the more important function which will do the bulk of the work.

wow, I was looking at tutorials for this a few days ago and couldnt find a great one. Thanks bogdan !

This is quite possibly the coolest thing I’ve ever seen

This was awesome thankyou :) I'd love more videos integrating with python please! PyO3's type mechanisms for guarding the GIL are unbelievably difficult to understand for more complex tasks... it uses `std::marker::PhantomData` which melted my brain a bit... I gave up trying to understand it.

This but a real life example where we can drop in rust for some kind of expensive function in prod and get some massive juicy speed up

concise and to the point

I've already done so from Java and Kotlin. It was even faster than calling normal c or c++ via JNI.

an example of using Python from Rust would also be interesting.

Great video!! Could you please talk about performance or any case that makes it necessary? Thanks!!!

The fact that Rust can build a C compatible shared library, which is what Rust calls a cdylib, is really important. This feature combined with FFI exports enables support not just for C and C++, but for a whole series of other programming languages too. And although I am still quite new to the Rust itself, this realization has already triggered me to explore several things. In this way I know that for Java there is really good JNI crate, and which is also really straightforward to use due to the abstractions in this crate. And if you have ever used JNI in C with the regular header files, and know how much of a serious pain that is to use, then it's actually really great what the authors of the crate have done. But since I am mostly a C# dotnet developer while not being scared to make make hands dirty on low level stuff, I also know how to use libraries with PInvoke, while taking care to use the Cdecl calling convention, mapping correct data type sizes and things like that.

My brother, u need some sleep. I understand the grind, but remember to get some rest as well!! Great video, going to use some ideas from this video in the project which I’m hoping to leverage into a job, so thank you for this

thank you for making this video

Waiting for this

I recently tried to use cgo to call rust in the go language, and it worked

Awesome!!!!

For a similar domain (data science & ML) but different language, check out Rust, Julia, and the Jlrs crate ! Two new languages, when used together, are insanely easy to prototype & develop with ❤

That is some beautiful tooling. I'm never using c extensions again!

Is there any difference between using `pyo3` and `rust-cython` when doing `maturn init`? From what I've understood of pyo3 its using rust-cython anyway. Is one of them more efficient or something.

Do Elixir NIFs next!

Does calling code like this improve the performance or we're still limited by GIL? For instance, can we benefit from Rust's concurrency and all the other good stuff similar to what Numpy and PyTorch are doing or Python's interpreter gets in the way?

I can't help see when you call `maturin develop` there's a mention of CPython. What is actually happening? Is maturin converting rust code to C code or is it running truly as rust code?

@Alche_mist

Жыл бұрын

I'm not sure if it's what you want to know, but CPython is the standard interpreter for Python (which itself is written in C). So I'd expect maturin to just hook into CPython (the interpreter) with some commands like "if you notice functions exposed from the Rust package being called, call them in the compiled Rust crate here".

I vote for Javascript as next

I want to see the way rust is comile to wasm and them being interoperated by other language. that will apply to more scenarios

please do c from rust

Writing Python modules in Rust is dead easy. Searched on Ruby modules and it is much more complicated.

Realy excelent video, but how about call C++ libraries on Rust, because are a lot of ML implementations but they are on C++.

You probably sound like you're talking in another language to anyone who isn't super familiar with these technical terms.

Replace your Python code with Rust.

To bad you have to specifically wrap the Rust code. That limits the possible use. It would be better if Python could simply use Rust object code.

This is basically how every big Python library works. Python is slow and therefore libraries like numpy have to be written in another language but still have to be provided to Python. It’s basically C/C++ code hidden behind a Python interface. This is the same just with Rust.
