For using large C dependencies within Rust, `bindgen` is also a very nice option.

https://rust-lang.github.io/rust-bindgen/

It does not attempt to help you refactor the C code, but it is still a great way to call your C library from Rust while you are in the process of refactoring. It can also work with `no_std` environments with a bit of configuring.

Bindgen is very nice for getting the C header into Rust, but it’s very much direct FFI.

What I got from this post is that c2rust wants to take it a step further and try to produce more idiomatic Rust, which is a very cool goal.

Yeah, it took me awhile to realize that was the project's goal. It's very ambitious and a terrifically cool idea.

I really, _really_ want the opposite of this. Generating C from Rust, so that I can compile it for platforms which have no prayer of getting Rust support anytime soon or where a specific certified C toolchain has to be used.

Nice! While being able to organize header declarations in submodules was very useful, deduplication like this is a godsend.
