Function bevy::tasks::futures_lite::future::try_zip

pub fn try_zip<T1, T2, E, F1, F2>(
    future1: F1,
    future2: F2,
) -> TryZip<F1, T1, F2, T2>

Expand description

Joins two fallible futures, waiting for both to complete or one of them to error.


use futures_lite::future;

let a = async { Ok::<i32, i32>(1) };
let b = async { Err::<i32, i32>(2) };

assert_eq!(future::try_zip(a, b).await, Err(2));
