Struct packet_stream::ClosePs

pub struct ClosePs<R: AsyncRead, W, B>(_);

Future for closing the packet-stream, indicating that no more packets will be sent.

This does not immediately close if there are still unfinished Requests, PeerResponses or PsSinks. In that case, the closing happens when the last of them finishes.

The error contains a None if an Request, PeerResponse or PsSink errored previously.
