RecoverWithRetries allows to switch to alternative Source on flow failure. It will stay in effect after a failure has been recovered up to attempts number of times so that each time there is a failure it is fed into the partialFunc and a new Source may be materialized. Note that if you pass in 0, this won't attempt to recover at all. Passing in -1 will behave exactly the same as RecoverWithRetriesTOut, TMat, TClosed(SubFlowTOut, TMat, TClosed, FuncException, IGraphSourceShapeTOut, TMat, Int32).

Since the underlying failure signal onError arrives out-of-band, it might jump over existing elements. This stage can recover the failure signal, but not the skipped elements, which will be dropped.

Emits when element is available from the upstream or upstream is failed and element is available from alternative Source

Backpressures when downstream backpressures

Completes when upstream completes or upstream failed with exception partialFunc can handle

Cancels when downstream cancels
