   1 //! Platform-specific types, as defined by C.
   2 //!
   3 //! Code that interacts via FFI will almost certainly be using the
   4 //! base types provided by C, which aren't nearly as nicely defined
   5 //! as Rust's primitive types. This module provides types which will
   6 //! match those defined by C, so that code that interacts with C will
   7 //! refer to the correct types.
