Crabs in Snakes!
summary
Shows how to compile Rust into a Python extension using PyO3 and the Rust toolchain (rustup, Cargo) and how to build/distribute with Maturin (use maturin develop locally and maturin generate-ci for CI). A straight rewrite of a hot path yields ~6× speedup on a contract that previously took over six minutes; releases publish ~50 prebuilt wheels per version. Demonstrates type conversions (i32 overflow raises a Python OverflowError) and the minimal boilerplate needed to import a compiled module.
