How to Call Rust from Python

A practical guide to integrating Rust into Python projects using PyO3 and maturin. Covers setup, a hello-world example, and a text-processing benchmark comparing pure Python, single-threaded Rust, and parallelised Rust with Rayon. Results show Rust single-threaded is ~1.7x faster than Python, and Rust with Rayon is ~2.3x faster, achieved with minimal code changes.
