How do I access the data sent over UDP?


Looking at the documentation, I can only find a way to return the size of the content sent over UDP:
Receives data from the socket. On success, returns the number of bytes read and the address from whence the data came.
Is there currently a way to output the content?
fn recv_from(&self, buf: &mut [u8]) -> Result<(usize, SocketAddr)>
The data is read into the start of buf. Thus, the data read can be accessed as a &[u8] like so:
match socket.recv_from(buf) {
Ok((bytes_read, _)) => Some(&buf[0..bytes_read]),
Err(_) => None,
}
