Struct futures::future::FlattenStream [−][src]
#[must_use = "streams do nothing unless polled"]pub struct FlattenStream<Fut> where
Fut: Future, { /* fields omitted */ }
Future for the flatten_stream combinator, flattening a
future-of-a-stream to get just the result of the final stream as a stream.
This is created by the Future::flatten_stream method.
