Akka.NETFlowOperationsConflateTIn, TOut, TMat Method
Allows a faster upstream to progress independently of a slower subscriber by conflating elements into a summary until the subscriber is ready to accept them. For example a conflate step might average incoming numbers if the upstream publisher is faster. This version of conflate does not change the output type of the stream. See ConflateWithSeedTIn, TOut, TMat, TSeed(FlowTIn, TOut, TMat, FuncTOut, TSeed, FuncTSeed, TOut, TSeed) for a more flexible version that can take a seed function and transform elements while rolling up. This element only rolls up elements if the upstream is faster, but if the downstream is faster it will not duplicate elements.

Emits when downstream stops backpressuring and there is a conflated element available

Backpressures when never

Completes when upstream completes

Cancels when downstream cancels
