Oh, that’s really cool. Rust noob here, and I hadn't seen the tooling for building Python bindings. That looks like it could be a very powerful way to speed up your Python programs (much easier than the “just replace the slow bits in C” advice that was standard.)

The mappings in https://github.com/kylebarron/geopolars/blob/master/py-geopo... for example look very easy to follow.
