Python in Rust

Hio three is a project that allows you to basely use a these type of things. It's almost like a function decorator. These are called procedure macros. They're kind of tricky to write, but they're really easy to use. And then there's another project in here called maturin. The tooling around building extensions for python in rust,. or calling python from rust, is getting so good and so easy  that i find this preferable to writing extension code on my own.
