source · 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.
§Examples
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));
