Akka.NETSourceOperationsWatchTerminationTOut, TMat, TMat2 Method
Materializes to TaskTResult that completes on getting termination message. The task completes with success when received complete message from upstream or cancel from downstream. It fails with the same error when received error message from downstream. It is recommended to use the internally optimized LeftTLeft, TRight(TLeft, TRight) and RightTLeft, TRight(TLeft, TRight) combiners where appropriate instead of manually writing functions that pass through one of the values.
