Rust has been doing that since day one. What makes this incremental compilation different from that of, say, Go, is that it works inside a package. Before incremental compilation, Rust and Go had the exact same model: package-at-a-time compilation. With incremental compilation, Rust is more fine-grained than that: Rust can compile specific parts of a package while leaving the other parts untouched.
