Function unix_recvmsg 

pub async fn unix_recvmsg<B: BufMut>(
    socket: &mut UnixStream,
    buf: &mut B,
) -> Result<(usize, ConnectionAddress)>

Receives data from the Unix domain socket.

This function is specifically for Unix domain sockets in stream mode (i.e. SOCK_STREAM), which are represented via UnixStream in tokio.

On success, returns the number of bytes read and the address from whence the data came.

Errors

If the underlying system call fails, an error is returned.
