final class MergePreferred[T] extends GraphStage[MergePreferredShape[T]]

Merge several streams, taking elements as they arrive from input streams (picking from preferred when several have elements ready).

A MergePreferred has one out port, one preferred input port and 1 or more secondary in ports.

Emits when one of the inputs has an element available, preferring a specified input if multiple have elements available

Backpressures when downstream backpressures

Completes when all upstreams complete (eagerComplete=false) or one upstream completes (eagerComplete=true), default value is false

Cancels when downstream cancels
