Struct TryParallelBufferUnordered 

Source 
pub struct TryParallelBufferUnordered<St>(/* private fields */)
where
    St: TryStream,
    St::Ok: TryFuture<Error = St::Error> + Send + 'static,

Expand description

Given a TryStream where every item is a TryFuture, this stream buffers up to a certain number of futures, runs them in parallel on separate tasks, and returns the results of the futures in completion order.

If any of the futures returns an error or panics, all other futures and tasks are immediately cancelled and the error/panic gets returned immediately.

This stream is cancellation safe if the inner stream and generated futures are also cancellation safe. This means that dropping this stream will also cancel any outstanding tasks and drop the relevant futures/streams.

You can use TryParallelBufferUnordered::awaiting_completion to control whether we wait for all tasks to fully terminate before this stream is considered to have ended.
