Partition

object Partition

Fan-out the stream to several streams. emitting an incoming upstream element to one downstream consumer according to the partitioner function applied to the element

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

Backpressures when one of the outputs backpressure

Completes when upstream completes

Cancels when when any (eagerCancel=true) or all (eagerCancel=false) of the downstreams cancel
