Description

End the current substream whenever a predicate returns true, starting a new substream for the next element.

emits when an element passes through. When the provided predicate is true it emits the element * and opens a new substream for subsequent element

backpressures when there is an element pending for the next substream, but the previous is not fully consumed yet, or the substream backpressures

completes when upstream completes (Until the end of stream it is not possible to know whether new substreams will be needed or not)
