Struct timely::container::flatcontainer::ResultRegion

source ·
pub struct ResultRegion<T, E> { /* private fields */ }
Expand description

A region to hold Results.

§Examples

Add results to a result region:

use flatcontainer::{Containerized, Push, Region, ResultRegion};
let mut r =
    <ResultRegion<<() as Containerized>::Region, <String as Containerized>::Region>>::default();

let ok_index = r.push(Result::<(), String>::Ok(()));
let err_index = r.push(Result::<(), String>::Err("Error".to_string()));

assert_eq!(Ok(()), r.index(ok_index));
assert_eq!(Err("Error"), r.index(err_index));
