Akka.NETSourceOperationsAggregateAsyncTOut1, TOut2, TMat Method
Similar to AggregateTOut1, TOut2, TMat(SourceTOut1, TMat, TOut2, FuncTOut2, TOut1, TOut2) but with an asynchronous function. Applies the given function towards its current and next value, yielding the next current value. If the function fold returns a failure and the supervision decision is Restart current value starts at zero again the stream will continue.

Emits when upstream completes

Backpressures when downstream backpressures

Completes when upstream completes

Cancels when downstream cancels
