Enum actix_utils::future::Either[−][src]

pub enum Either<L, R> {
    Left {
        value: L,
    },
    Right {
        value: R,
    },
}

Combines two different futures that have the same output type.

Construct variants with Either::left and Either::right.

Examples

use actix_utils::future::{ready, Ready, Either};

let res = Either::<_, Ready<usize>>::left(ready(42));
assert_eq!(res.await, 42);

let res = Either::<Ready<usize>, _>::right(ready(43));
assert_eq!(res.await, 43);

Variants

Left

A value of type L.

Fields of Left

value: L
Right

A value of type R.

Fields of Right

value: R
