Struct futures::stream::Zip [−][src]
#[must_use = "streams do nothing unless polled"]pub struct Zip<St1, St2> where
St1: Stream,
St2: Stream, { /* fields omitted */ }
An adapter for merging the output of two streams.
The merged stream produces items from one or both of the underlying streams as they become available. Errors, however, are not merged: you get at most one error at a time.
