Whether you are rebuilding a bottlenecked web service (moving from FastAPI to Actix), accelerating a data pipeline (moving from Pandas to Polars), or rewriting a CLI utility, the performance gains are massive. Rust services routinely run 10x to 100x faster while consuming a fraction of the RAM. But once you install Rust and set up your Cargo.toml , you hit the first roadbl...
