[][src]Struct futures::stream::Select

#[must_use = "streams do nothing unless polled"]
pub struct Select<S1, S2> { /* fields omitted */ }

An adapter for merging the output of two streams.

The merged stream produces items from either of the underlying streams as they become available, and the streams are polled in a round-robin fashion. Errors, however, are not merged: you get at most one error at a time.
