[−][src]Struct epoxy_streams::Subscription
A Subscription object ties a stream to a listener function such that the listener function is run whenever a new value is added to the stream. When the Subscription object is destroyed the listener function will stop getting called.
Examples
let stream_host: epoxy_streams::Sink<i32> = epoxy_streams::Sink::new(); let stream = stream_host.get_stream(); { let _subscription = stream.subscribe(|val| {val;}); assert_eq!(stream.count_subscribers(), 1); } assert_eq!(stream.count_subscribers(), 0);
