Attributes
Aggregates elements of this stream using the provided sink for as long as the downstream operators on the stream are busy.
Aggregates elements of this stream using the provided sink for as long as the downstream operators on the stream are busy.
This operator divides the stream into two asynchronous "islands". Operators upstream of this operator run on one fiber, while downstream operators run on another. Whenever the downstream fiber is busy processing elements, the upstream fiber will feed elements into the sink until it signals completion.
Any sink can be used here, but see ZSink.foldWeightedZIO and ZSink.foldUntilZIO for sinks that cover the common usecases.
