Function similar::utils::diff_slices

pub fn diff_slices<'x, T: PartialEq + Hash + Ord>(
    alg: Algorithm,
    old: &'x [T],
    new: &'x [T],
) -> Vec<(ChangeTag, &'x [T])>

Shortcut for diffing two slices.

This function produces the diff of two slices and returns a vector with the changes.

use similar::{Algorithm, ChangeTag};
use similar::utils::diff_slices;

let old = "foo\nbar\nbaz".lines().collect::<Vec<_>>();
let new = "foo\nbar\nBAZ".lines().collect::<Vec<_>>();
assert_eq!(diff_slices(Algorithm::Myers, &old, &new), vec![
    (ChangeTag::Equal, &["foo", "bar"][..]),
    (ChangeTag::Delete, &["baz"][..]),
    (ChangeTag::Insert, &["BAZ"][..]),
]);
