Akka.NETSourceOperationsConflateWithSeedTOut, TMat, TSeed 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 allows to derive a seed from the first element and change the aggregated type to be different than the input type. See ConflateTOut, TMat(SourceTOut, TMat, FuncTOut, TOut, TOut) for a simpler version that does not change types. 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

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type SourceTOut, TMat. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
