I worked on a Rust project at work for several months. Compile times were not a significant issues for developers where it was generally cached. For example, repeatedly running a test only compiled a small amount of code.

It was a bit slow in CI/CD build environments with no cache, but so are the k8s Go projects I work on (go mod pulling in the world).

The only thing approaching 2 hours I've ever seen is building the compiler from scratch.
