[−][src]Struct futures_util::stream::ForEachConcurrent

#[must_use = "streams do nothing unless polled"]

pub struct ForEachConcurrent<St, Fut, F> { /* fields omitted */ }

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

This structure is returned by the StreamExt::for_each_concurrent method.
