Have you ever found yourself writing essentially the same code twice, once for
RawFd for Posix-ish platforms and once for RawHandle or RawSocket
for Windows platforms? This crate abstracts over those platform differences.
Being non-owning, these handles operate much like raw pointers in Rust. They are considered safe to construct, but unsafe to use in any way that depends on the resource they point to.
For a safe owning API, see the io-streams crate.
