final class Broadcast[T] extends GraphStage[UniformFanOutShape[T, T]]

Fan-out the stream to several streams emitting each incoming upstream element to all downstream consumers. It will not shut down until the subscriptions for at least two downstream subscribers have been established.

Emits when all of the outputs stops backpressuring and there is an input element available

Backpressures when any of the outputs backpressure

Completes when upstream completes

Cancels when If eagerCancel is enabled: when any downstream cancels; otherwise: when all downstreams cancel
