pybind11 VS setuptools-rust

Just use https://github.com/pybind/pybind11 . Your life will be a lot simpler that way.

Some work on the C++ side will be required. There's https://github.com/pybind/pybind11 for example.

Also if you need to write libraries for Python in C++: https://github.com/pybind/pybind11

You should also be aware of pybind11, which makes calling c++ code from python (or vice-versa) a fairly straightforward task, if this becomes necessary or convenient.

Pybind11 is what you are looking for.

pybind11

This was not my information at the time. But thanks for the info, it is helpful.

With https://github.com/pybind/pybind11 there is really great integration with C++ and Python is my second home after C++ actually.

Anyway, I am quite happy with Wren and it seems to be fast (not a requirement for my project, though)

Managed to dig up the issue: https://github.com/pybind/pybind11/issues/1262

For Python specifically, In addition to using rust-cpython or PyO3, maturin makes it really comfortable to build, package, and publish Rust code into Python packages and, if your niche doesn't quite fit, there's setuptools-python which might do it.

Aside from the PyO3 and rust-cpython crates already mentioned, I'd suggest maturin as a way to integrate your build processes or possibly setuptools-rust.

Compiled modules for Python stuff (I'd recommend PyO3 but the last one I started was before that worked on stable Rust, so I used its progenitor, rust-cpython. See also maturin or setuptools-rust).

...but you will need to rename the generated library to match import conventions. setuptools-rust or Maturin can help with that.

Between pyodide, pyo3, rust-cpython, and rustpython, I think Pyo3 is the best way to drop in rust in a python project for a speed up, if that is your goal. Some of the demos show using python from rust, but to me the biggest feature is without a doubt compiling rust code to native python modules. I'm using it to speed up image manipulation backed by numpy arrays.

There’s a setuptools rust [0] extension package that can be used to hook the compilation of the rust into the wheel building or install from source. Maturin [1] seems to be regarded as the new and improved solution for this, but I found that it’s angled toward the using python from rust.

There’s also the rust numpy [2] package by the same org which is fantastic in that it lets you pass a numpy matrix to a native method written in rust and convert it to the rust equivalent data structure, perform whatever transformation you want (in parallel using rayon [3]), and return the array. When building for release, I was seeing speed ups of 100x over numpy on the most matrix mathable function imaginable, and numpy is no joke.

I think there is a lot of potential for these two ecosystems together. If there’s not a python package for something, there’s probably a rust crate.

If anyone is interested the python package that I'm building with some rust backend, its called pyrogis [4] for making custom image manipulations through numpy arrays.
