So now you're writing two compilers.

What did you actually gain from this, outside of more work?

Writing a small compiler in C and a big compiler in Rust is simpler than writing a big compiler in C.

But writing a Rust compiler in Rust is already done.

Writing programs in Rust is not simpler then writing programs in C.

You can now have trustworthy Rust compiler binaries, through the work of the Bootstrappable Builds community, which found a way to build a C compiler without having C compiler binaries yet.

Two simpler pieces of work as opposed to one complex one. Even if the two parts might be more volume, they're both easier to write and debug.

You often write two compilers when trying to bootstrap a C compiler, as GCC used to do. Often, it's a very simple version of the language implemented in the architecture's assembly.

Even if it is a bit more work:

- you can write the bulk of your code in a language you prefer over C

- you end up with a self-hosting rust compiler
