| SourceOperationsConflateTOut, 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
ConflateWithSeedTOut, TMat, TSeed(SourceTOut, 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
