Struct futures_util::stream::ForEachConcurrent

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

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

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

type Error = S::Error

An error

fn poll(&mut self, cx: &mut Context) -> Poll<S, S::Error>

Attempt to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.
