[−][src]Struct gatherr::Gatherr

pub struct Gatherr<T, E>(pub Result<T, E>);

A newtype implementing FromIterator to collect into a result preserving all error values, instead of just the first as FromIterator for Result does

let v = vec![Ok("a"), Err(1), Ok("b"), Err(2)];

let Gatherr(result): Gatherr<Vec<&str>, Vec<u32>>
    = v.into_iter().collect();

assert_eq!(result, Err(vec![1, 2]));

Using this directly can be awkward due to the necessary additional type annotation. Consider using the extension trait method or the freestanding gatherr function instead
