async fn query_nameserver_udp(
address: SocketAddr,
serialised_request: &mut [u8],
) -> Option<Message>Expand description
Send a message to a remote nameserver over UDP, returning the
response. If the message would be truncated, or an error occurs
while sending it, None is returned. Otherwise the deserialised
response message is: but this response is NOT validated -
consumers MUST validate the response before using it!
This has a 5s timeout.
