Module ffi

Platform-specific types, as defined by C.

Code that interacts via FFI will almost certainly be using the base types provided by C, which aren’t nearly as nicely defined as Rust’s primitive types. This module provides types which will match those defined by C, so that code that interacts with C will refer to the correct types.
