Crate iter_diff

Differences between iterators

The IterDiff trait can be used to iterate through the differences between two iterators. The differences between each element are enumerated by Diff. The variants of the enum express the changes one would need to make to the original iterator in order to attain the second.

use iter_diff::prelude::*;

let a = [0, 1, 2, 3];
let b = [0, 2, 2];

let diffs: Vec<_> = a.iter_diff(b).collect();
assert_eq!(diffs.len(), 4);

assert_eq!(diffs[0], Diff::Keep);
assert_eq!(diffs[1], Diff::Change(2));
assert_eq!(diffs[2], Diff::Keep);
assert_eq!(diffs[3], Diff::Remove);
