It basically automates everything for you. If you use it with Github actions, it will compile wheels for you on each release for every platform and python version you want, and even upload them to PyPi (pip) for you. Everything feels very modern and well thought out. People really care about good tooling in the Rust world.
I got the idea from CMake, which also has absolutely nothing to do with Python but is best installed via Pip. It's a package manager that basically works and is basically always available on Linux and Mac (among programmers anyway).
One of the few areas of Python that doesn't completely suck.
What's the best way to learn enough Rust to do this? My code is basically just some Numpy array manipulation, with some unfortunate for-loops which can't be vectorized, which is the source of the slow speeds.
I've found Chat GPT to be really excellent for quickly getting myself up to speed with languages that I'm not familiar with.
I will search myself, but is there are a great rust syntax reference doc?
If you actually want to learn rust then that’s a different story and you should probably check out Steve Klabnik‘s book or something like that (or just look at the sample code I linked to in my other comment from my own recent rust library for python).

Basically you use ndarray instead of numpy, try to vectorize anything you can, and for the for loops that can’t be vectorized, you can use rayon to do them in parallel.
(yes, this particular bit of rust evangelism was not obvious from the headline)
