final class ZipLatest[A, B] extends ZipLatestWith2[A, B, (A, B)]

Combine the elements of 2 streams into a stream of tuples, picking always the latest element of each.

A ZipLatest has a left and a right input port and one out port.

No element is emitted until at least one element from each Source becomes available.

Emits when all of the inputs have at least an element available, and then each time an element becomes * available on either of the inputs

Backpressures when downstream backpressures

Completes when any upstream completes

Cancels when downstream cancels

    Add the given attributes to this Graph.

    Add the given attributes to this Graph. If the specific attribute was already present on this graph this means the added attribute will be more specific than the existing one. If this Source is a composite of multiple graphs, new attributes on the composite will be less specific than attributes set directly on the individual graphs of the composite.
