Function futures::stream::select_all

pub fn select_all<I>(streams: I) -> SelectAll<<I as IntoIterator>::Item> where
    I: IntoIterator,
    <I as IntoIterator>::Item: Stream,
    <I as IntoIterator>::Item: Unpin, 

Convert a list of streams into a Stream of results from the streams.

This essentially takes a list of streams (e.g. a vector, an iterator, etc.) and bundles them together into a single stream. The stream will yield items as they become available on the underlying streams internally, in the order they become available.

Note that the returned set can also be used to dynamically push more futures into the set as they become available.
