Rust has a fairly powerful incremental compilation engine, so it tries to avoid re-computing checks if the relevant code hasn't changed. In practice it still recomputes a lot of stuff though. It's not that relevant though, because the longest part of any Rust build is the dependencies, and those are never recompiled. Most projects compile relatively fast once you've built them once.
