I've got a pretty large Rust/Tauri program going. Breaking things into crates help, but if you touch enough bits of common libraries, everything needs to get rebuilt anyway.

I use Makefiles for everything. What I found helps is breaking out the parts that don't change much into separate Make commands (like generating icons, linting, frontend, tests, etc), then leaving "make go" as the simplest inner iteration loop. That way, it's a lot more bearable.

There's also "make build" and "make fullclean." You start one of those and take a long break.
