C2Rust Transpiler

• c2rust

  Migrate C code to Rust

  

In the chart at [1], this step is represented by a magic wand.

(I wanted to give some examples, but https://c2rust.com/ seems to not be translating today.)

  Discontinued libyaml transpiled to rust by c2rust

I used it with great success for transpiring libyaml from C to Rust. I even set up Miri to run the upstream library's entire transpiled test suite, and the fact it passes is validation of absence of UB in the original C code.

The transpiled library now serves as the YAML backend for the widely used serde_yaml crate. Having serde_yaml be pure-Rust code instead of linking C is advantageous for painless cross-compilation as well as making downstream projects runnable in Miri.

• cargo-zigbuild

  19 1,181 8.6 Rust

  Compile Cargo project with zig as linker

  

Zig also takes this approach, and even exposes its C compiler (which if I recall correctly is basically Clang plus diverse sysroots and other customisation out of the box) as a separate `zig cc`.

I do a lot of work in Rust, and cross-compilation can be a pain when you have a lot of C dependencies. Fortunately https://github.com/messense/cargo-zigbuild exists. It sounds crazy, but using Zig's inbuilt C compiler to help build my Rust projects has been the smoothest option I've found.

I can't help but wonder if it would be worth it for Rust to follow D and Zig by shipping its own inbuilt C compiler, even if they still want to also support external C toolchains. It should be roughly the same effort as it was for Zig, given that they both use LLVM.

> Zig also takes this approach

D took the much more fun way, which is to implement a new C parser from scratch and tweak the D lexer and semantics to handle the differences of C. It's not too bad, about 5000 lines of D:

Best of all, it's Boost licensed, meaning anyone can use it for any purpose, even commercial use.
