    interface: &Ipv4Addr
) -> Result<()>

Executes an operation of the IP_ADD_MEMBERSHIP type.

This function specifies a new multicast group for this socket to join. The address must be a valid multicast address, and interface is the address of the local interface with which the system should join the multicast group. If it's equal to INADDR_ANY then an appropriate interface is chosen by the system.

fn take_error(&self) -> Result<Option<Error>>

Get the value of the SO_ERROR option on this socket.

This will retrieve the stored error in the underlying socket, clearing the field in the process. This can be useful for checking errors between calls.

fn connect<A: ToSocketAddrs>(&self, addr: A) -> Result<()>

Connects this UDP socket to a remote address, allowing the send and recv syscalls to be used to send data and also applies filters to only receive data from the specified address.

fn send(&self, buf: &[u8]) -> Result<usize>

Sends data on the socket to the remote address to which it is connected.

The connect method will connect this socket to a remote address. This method will fail if the socket is not connected.
