//! Networking primitives. //! //! The types provided in this module are non-blocking by default and are //! designed to be portable across all supported Mio platforms. As long as the //! [portability guidelines] are followed, the behavior should be identical no //! matter the target platform. //! //! [portability guidelines]: ../struct.Poll.html#portability //! //! # Notes //! //! When using a datagram based socket, i.e. [`UdpSocket`] or [`UnixDatagram`], //! its only possible to receive a packet once. This means that if you provide a //! buffer that is too small you won't be able to receive the data anymore. How //! OSs deal with this situation is different for each OS: //! * Unixes, such as Linux, FreeBSD and macOS, will simply fill the buffer and //! return the amount of bytes written. This means that if the returned value //! is equal to the size of the buffer it may have only written a part of the //! packet (or the packet has the same size as the buffer). //! * Windows returns an `WSAEMSGSIZE` error. //! //! Mio does not change the value (either ok or error) returned by the OS, it's //! up to the user handle this. How to deal with these difference is still up //! for debate, specifically in //! . The best advice we can //! give is to always call receive with a large enough buffer. mod tcp; pub use self::tcp::{TcpListener, TcpStream}; mod udp; pub use self::udp::UdpSocket; #[cfg(unix)] mod uds; #[cfg(unix)] pub use self::uds::{SocketAddr, UnixDatagram, UnixListener, UnixStream};
