Hi, do you know a nice minimal example that shows how to extend Guile with Rust to get maximum performance for some tasks? I’m not looking for hints how to speed up Scheme code, or how to do less. Instead I want to learn how to do those cases where I actually need some specific algorithm at maximum speed — and want to implement it in Rust. Ideally with a fast Scheme-to-Rust-to-Scheme interface (similar to the native C arrays numpy exposes to C that allow getting the speed of C).
