Cache 🔒
It is a well known fact that rustc is not the fastest compiler in the world. What is less known is that even rustc --version --verbose takes about a hundred milliseconds! Because we need compiler version info even for no-op builds, we cache it here, based on compiler’s mtime and rustup’s current toolchain.
