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.
