Zips this stream together with the index of elements.
Zips the two streams so that when a value is emitted by either of the two streams, it is combined with the latest value from the other stream to produce a result.
Zips the two streams so that when a value is emitted by either of the two streams, it is combined with the latest value from the other stream to produce a result.
Note: tracking the latest value is done on a per-chunk basis. That means that emitted elements that are not the last value in chunks will never be used for zipping.
