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

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

A stream combinator which executes a unit closure over each item on a stream.

This structure is returned by the Stream::for_each method.
