Signals are sent from Sources to Sinks to inform them of changes.
Remarks
A Source, when consumed, sends a sequence of events to Sinks. In order, a
Start signal will always be sent first, followed optionally by one or
more Push signals, carrying values and representing the stream. A
Source will send the End signal when it runs out of values. The
End signal will be omitted if the Source is cancelled by a
Close signal, sent back from the Sink.
