Implementations
Wait for session status to change
Return Self
on error so that you can handle the error and restart
the operation.
If the server close the connection without sending anything,
this function would return Ok(None)
.
Since waiting for the remote child to exit is basically waiting for the socket to become readable, try_wait is basically polling for readable.
If it is readable, then it would read the entire packet in blocking manner. While this is indeed a blocking call, it is unlikely to block since the ssh multiplex master most likely would send it using one write/send.
And even if it does employ multiple write/send, these functions would just return immediately since the buffer for the unix socket is empty and should be big enough for one packet.
If it is not readable, then it would return Ok(InProgress).
