Trait futures_concurrency::prelude::_

pub trait _ {
    type Output;
    type Future: Future<Output = Self::Output>;
    fn join(self) -> Self::Future;
}

Wait for multiple futures to complete.

Awaits multiple futures simultaneously, returning the output of the futures once both complete.

Associated Types

type Output

The resulting output type.

type Future: Future<Output = Self::Output>

The resulting joined future.

Required methods

fn join(self) -> Self::Future

Waits for multiple futures to complete.

Awaits multiple futures simultaneously, returning the output of the futures once both complete.

This function returns a new future which polls both futures concurrently.
