Function futures::stream::futures_unordered

pub fn futures_unordered<I>(futures: I) -> FuturesUnordered<I::Item::Future> where I: IntoIterator, I::Item: IntoFuture

Converts a list of futures into a Stream of results from the futures.

This function will take an list of futures (e.g. a vector, an iterator, etc), and return a stream. The stream will yield items as they become available on the futures internally, in the order that they become available. This function is similar to buffer_unordered in that it may return items in a different order than in the list specified.

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