# Function futures_util::future::join [−] [src]

###

    pub fn join<Fut1, Fut2>(future1: Fut1, future2: Fut2) -> Join<Fut1, Fut2>ⓘNotable traits for Join<Fut1, Fut2>impl<Fut1: Future, Fut2: Future> Future for Join<Fut1, Fut2>    type Output = (Fut1::Output, Fut2::Output); where
        Fut1: Future,
        Fut2: Future,

Joins the result of two futures, waiting for them both to complete.

This function will return a new future which awaits both futures to complete. The returned future will finish with a tuple of both results.

Note that this function consumes the passed futures and returns a wrapped version of it.

# Examples

    use futures::future;

    let a = async { 1 };
    let b = async { 2 };
    let pair = future::join(a, b);

    assert_eq!(pair.await, (1, 2));
