Types that implement this are capable of sending a serialized DNS message on a stream

The underlying Stream implementation should yield Some(()) whenever it is ready to send a message, NotReady, if it is not ready to send a message, and Err or None in the case that the stream is done, and should be shutdown.

Required methods

fn send_message(&mut self, message: DnsRequest) -> DnsResponseFutureⓘ

Notable traits for DnsResponseFuture

impl Future for DnsResponseFuture type Output = Result<DnsResponse, ProtoError>;
[src]

Send a message, and return a future of the response

Return

A future which will resolve to a SerialMessage response

fn shutdown(&mut self)[src]

Allows the upstream user to inform the underling stream that it should shutdown.

After this is called, the next time poll is called on the stream it would be correct to return Poll::Ready(Ok(())). This is not required though, if there are say outstanding requests that are not yet complete, then it would be correct to first wait for those results.

fn is_shutdown(&self) -> bool[src]

Returns true if the stream has been shutdown with shutdown
