[][src]Struct tokio::prelude::stream::Fold

#[must_use = "streams do nothing unless polled"]
pub struct Fold<S, F, Fut, T> where
    Fut: IntoFuture
{ /* fields omitted */ }

A future used to collect all the results of a stream into one generic type.

This future is returned by the Stream::fold method.
