Enum itertools::Diff

pub enum Diff<I, J> where I: Iterator, J: Iterator {
    FirstMismatch(usize, PutBack<I>, PutBack<J>),
    Shorter(usize, PutBack<I>),
    Longer(usize, PutBack<J>),
}

A type returned by the diff_with function.

Diff represents the way in which the elements yielded by the iterator I differ to some iterator J.

Variants

FirstMismatch	The index of the first non-matching element along with both iterator's remaining elements starting with the first mis-match.
Shorter	The total number of elements that were in J along with the remaining elements of I.
Longer	The total number of elements that were in I along with the remaining elements of J.
