It's actually pretty easy. All you need is declare `extern "C" fn foo() -> T` to be able to call it from Rust, and to pass the link flags either by adding a #[link] attribute or by adding it in a build.rs. You can use the bindgen crate to generate bindings ahead of time, or in a build.rs and include!() the generated bindings. Normally what people do is create a `-sys` crate that contains only bindings, usually generated. Then their code can `use` the bindings from the sys crate as normal. > in contrast, in C++ and Objective C, all you need to do is include the right header and link against the library.
