[−][src]Struct post::subscriber::Subscription
Stream of messages from Publishers
The new function starts the process of subscribing to a publisher. A message could arrive at any point after the call completes. Subscription::wait_for_subscription_complete can be used to listen for the subscription acknowledgement.
All inbound messages are handled during the stream poll. This can mean that a subscriber not handling messages can be deemed in active and it's subscription ended.
The primary means of interacting with a Subscription is through the futures::stream::Stream impl.
