Rust abstractions for kernel sources

Which leads me to believe I need to create some Rust abstractions so that I can call these C calls from within Rust. Problem is, I'm having difficulty figuring out how to properly build a Rust abstraction for kernel sources (a few functions within the net framework) and was hoping someone might know of a tutorial or some kind of g...
