You'd need the Rust compiler toolchain anyway, just to do the Rust-to-C conversion step instead of compiling to a binary library? What would be the point? The C ABI is quite compatible across toolchains.

The Rust-to-C conversion would be done by the Rust library author (or more likely, some automated CI process) to create a C source code distribution of the Rust library.
