gun_up - The connection is up


{gun_up, ConnPid, Protocol}

ConnPid  :: pid()
Protocol :: http | http2

The connection is up.

This message informs the owner process that the connection or reconnection completed.

Gun will now start processing the messages it received while waiting for the connection to be up. If this is a reconnection, then this may not be desirable for all requests. Those requests should be cancelled when the connection goes down, and any subsequent messages ignored.



The pid of the Gun connection process.


The protocol selected for this connection. It can be used to determine the capabilities of the server.
