| SubFlowOperationsWatchTerminationTOut, TMat, TMat2, TClosed 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.
