Module net

Available on crate feature net only.

Expand description

Network-related operations.

On Windows, one must call wsa_startup in the process before calling any of these APIs. wsa_cleanup may be used in the process if these APIs are no longer needed.

acceptfrom: accept(fd, &addr, &len)—Accepts an incoming connection and returns the peer address.
acceptfrom_with: accept4(fd, &addr, &len, flags)—Accepts an incoming connection and returns the peer address, with flags.
bind: bind(sockfd, addr)—Binds a socket to an IP address.
connect: connect(sockfd, addr)—Initiates a connection to an IP address.
connect_unspec: connect(sockfd, {.sa_family = AF_UNSPEC}, sizeof(struct sockaddr))— Dissolve the socket’s association.
getpeername: getpeername(fd, addr, len)—Returns the address a socket is connected to.
getsockname: getsockname(fd, addr, len)—Returns the address a socket is bound to.
listen: listen(fd, backlog)—Enables listening for incoming connections.
recv: recv(fd, buf, flags)—Reads data from a socket.
recvfrom: recvfrom(fd, buf, flags, addr, len)—Reads data from a socket and returns the sender address.
recvmsg: recvmsg(msghdr)—Receives a message from a socket.
send: send(fd, buf, flags)—Writes data to a socket.
sendmmsg: sendmmsg(msghdr)—Sends multiple messages on a socket.
sendmsg: sendmsg(msghdr)—Sends a message on a socket.
sendmsg_addr: sendmsg(msghdr)—Sends a message on a socket to a specific address.
sendto: sendto(fd, buf, flags, addr)—Writes data to a socket to a specific IP address.
shutdown: shutdown(fd, how)—Closes the read and/or write sides of a stream.
socket: socket(domain, type_, protocol)—Creates a socket.
socket_with: socket_with(domain, type_ | flags, protocol)—Creates a socket, with flags.
