Thanks, that's exactly what I wanted.

I hate C as a language, but I think it makes for a great API. Any language under the sun can bind to C. To bind to Rust or C++, you'd need to basically be a Rust/C++ compiler. From that perspective, I don't have a problem with having a Rust library with a C interface, except it might be harder to maintain for distros. gcc/g++ are everywhere at least.
