Struct futures::stream::Zip
[−]
[src]
#[must_use = "streams do nothing unless polled"]pub struct Zip<S1, S2> where
S1: Stream,
S2: 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.
