As Gecko is moving toward more Rust code, the cases where Rust and C code interoperate will become more common.
This document is an attempt to ease the learning curve for engineers facing it for the first time. It assumes no prior experience with cross-language C interfaces (called FFI).
It also assumes that Rust code is already built into Gecko. If you need help with that, read Introducing Rust code in Firefox.
