Enums

• AddressFamily
  These constants specify the protocol family to be used in socket and socketpair
• ControlMessage
  A type-safe zero-copy wrapper around a single control message, as used with sendmsg. More types may be added to this enum; do not exhaustively pattern-match it.
• ControlMessageOwned
  A type-safe wrapper around a single control message, as used with recvmsg.
• Shutdown
• SockProtocol
  Constants used in socket and socketpair to specify the protocol to use.
• SockType
  These constants are used to specify the communication semantics when creating a socket with socket()
• TlsGetRecordType
  These constants correspond to TLS 1.2 message types, as defined in RFC 5246, Appendix A.1

Traits

• GetSockOpt
  Represents a socket option that can be retrieved.
• SetSockOpt
  Represents a socket option that can be set.
• SockaddrLike
  Anything that, in C, can be cast back and forth to sockaddr.

Functions

• accept
  Accept a connection on a socket
• accept4
  Accept a connection on a socket
• bind
  Bind a name to a socket
• connect
  Initiate a connection on a socket
• getpeername
  Get the address of the peer connected to the socket fd.
• getsockname
  Get the current address to which the socket fd is bound.
• getsockopt
  Get the current value for the requested socket option
• listen
  Listen for connections on a socket
• recv
  Receive data from a connection-oriented socket. Returns the number of bytes read
• recvfrom
  Receive data from a connectionless or connection-oriented socket. Returns the number of bytes read and, for connectionless sockets, the socket address of the sender.
• recvmmsg
  An extension of recvmsg that allows the caller to receive multiple messages from a socket using a single system call.
• recvmsg
  Receive message in scatter-gather vectors from a socket, and optionally receive ancillary data into the provided buffer. If no ancillary data is desired, use () as the type parameter.
• send
  Send data to a connection-oriented socket. Returns the number of bytes read
• sendmmsg
  An extension of sendmsg that allows the caller to transmit multiple messages on a socket using a single system call. This has performance benefits for some applications.
• sendmsg
  Send data in scatter-gather vectors to a socket, possibly accompanied by ancillary data. Optionally direct the message at the given address, as with sendto.
• sendto
  Send a message to a socket
• setsockopt
  Sets the value for the requested socket option
• shutdown
  Shut down part of a full-duplex connection.
• socket
  Create an endpoint for communication
• socketpair
  Create a pair of connected sockets

Type Aliases

• sa_family_t

Unions

• SockaddrStorage
  A container for any sockaddr type
