Module net

Networking primitives for TCP/UDP communication.

This module provides networking functionality for the Transmission Control and User Datagram Protocols, as well as types for IP and socket addresses.

Organization

• TcpListener and TcpStream provide functionality for communication over TCP
• UdpSocket provides functionality for communication over UDP
• IpAddr represents IP addresses of either IPv4 or IPv6; Ipv4Addr and Ipv6Addr are respectively IPv4 and IPv6 addresses
• SocketAddr represents socket addresses of either IPv4 or IPv6; SocketAddrV4 and SocketAddrV6 are respectively IPv4 and IPv6 socket addresses
• ToSocketAddrs is a trait that is used for generic address resolution when interacting with networking objects like TcpListener, TcpStream or UdpSocket
• Other types are return or parameter types for various methods in this module

Rust disables inheritance of socket objects to child processes by default when possible. For example, through the use of the CLOEXEC flag in UNIX systems or the HANDLE_FLAG_INHERIT flag on Windows.

Structs

AddrParseError

An error which can be returned when parsing an IP address or a socket address.

Incoming

An iterator that infinitely accepts connections on a TcpListener.

Ipv4Addr

An IPv4 address.

Ipv6Addr

An IPv6 address.

SocketAddrV4

An IPv4 socket address.

SocketAddrV6

An IPv6 socket address.

TcpListener

A TCP socket server, listening for connections.

TcpStream

A TCP stream between a local and a remote socket.

UdpSocket

A UDP socket.

IntoIncomingExperimental

An iterator that infinitely accepts connections on a TcpListener.

Enums

IpAddr

An IP address, either IPv4 or IPv6.

Shutdown

Possible values which can be passed to the TcpStream::shutdown method.

SocketAddr

An internet socket address, either IPv4 or IPv6.

Ipv6MulticastScopeExperimental

Scope of an IPv6 multicast address as defined in IETF RFC 7346 section 2.

Traits

ToSocketAddrs

A trait for objects which can be converted or resolved to one or more SocketAddr values.
