Cache¶
Definition¶
Usage¶
Cache the latest emit - the result is suppressing multiple emits with the same value. Also initialization can be defined in the case the source publisher does not emit on subscription.
Usage:
>>> from broqer import Value, op, Sink
>>> s = Value(1)
>>> cached_publisher = s | op.Cache()
>>> _disposable = cached_publisher.subscribe(Sink(print))
1
>>> s.emit(2)
2
>>> s.emit(2)
>>> _disposable.dispose()
Using the initial value for cache:
>>> from broqer import Value, op, Sink
>>> s = Value()
>>> cached_publisher = s | op.Cache(1)
>>> _disposable = cached_publisher.subscribe(Sink(print))
1
>>> s.emit(1)
>>> s.emit(2)
2
>>> _disposable.dispose()
