combineCompleted

Replaces incomplete outcomes by the previous completed outcome, with the updated progress information.

For example, if the incoming iterable contains:

[Incomplete(loading(0.23%)), Success(5, Done), Incomplete(loading(0.5%))]

then this method returns:

[Incomplete(loading(0.23%)), Success(5, Done), Success(5, loading(0.5%))]

You can see how the last incomplete value has been transformed into a loading success. The same transformation is applied to failures.

This operator is useful when the iterable represents changes to a single value over time: when we receive an incomplete event, we merge it with the previous complete event to still display a value. For example, in a UI, this would allow displaying old values while refresh requests are ongoing.
