It's very slow for the initial revision, as it has to compile all its dependencies. From there, if you add in full async/await support with a web server framework, you're looking at ~6sec iteration time. If you bring in LLVM's LLD instead of GNU or MSVC, you can bring that down to ~3-4sec. They're working on adding support for their own LLVM competitor, Cranelift, that should further reduce those times. It's only intended for debug/development builds, though, so you'll still need longer compile times for release.
While the compile times are a bit slower, one of the advantages of the strict type system is you don't need to compile to an executable quite as often.
Most of the time your IDE's messages (or "cargo check" output) is sufficient to find all the things the compiler will complain about.
I usually find that once I've fixed all of those, I compile it once and it just works.
