A take while stage.
The given predicate
must be invoked on each element consumed. While the predicate returns true
,
the element must be emitted, when the predicate returns false
, the element must not be emitted,
downstream must be completed and upstream must be cancelled.
The predicate
must not be invoked again once it returns false
for the first time. Any elements
supplied by upstream before it handles the cancellation signal must be dropped.
Any RuntimeException
thrown by the predicate must be propagated downstream as an error, and upstream
must be cancelled. Any subsequent elements received from upstream before the cancellation signal is handled
must be dropped.
