Rust outputs prototype information in .rmeta artifacts that are generated as one of the first steps in compilation, so this is not a compile-time issue. AFAICT, dependencies are also tracked, and debug vs. release switches are provided that also control things like binary optimization.

The real "problem" for compile times in Rust is that Rust makes it idiomatic to write code that's slower to compile. That's really all there is to it. If you were to literally write Rust like it's C, you'd find that there's no real overhead introduced by Rust per se.

(This is not to say that improvement is not possible, of course. Even what's "idiomatic" can be tweaked over time to reduce the amount of excessive, duplicated work that the build system has to do. Newer features like const generics will probably make this feasible in the future, and improvements in the compile workflow itself will do the rest.)
