Function similar::utils::diff_lines

pub fn diff_lines<'x, T: DiffableStrRef + ?Sized>(
    alg: Algorithm,
    old: &'x T,
    new: &'x T,
) -> Vec<(ChangeTag, &'x T::Output)>

Shortcut for making a line diff.

This function produces the diff of two slices and returns a vector with the changes. Unlike diff_chars or diff_slices it returns a change tag for each line.

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

assert_eq!(diff_lines(Algorithm::Myers, "foo\nbar\nbaz\nblah", "foo\nbar\nbaz\nblurgh"), vec![
    (ChangeTag::Equal, "foo\n"),
    (ChangeTag::Equal, "bar\n"),
    (ChangeTag::Equal, "baz\n"),
    (ChangeTag::Delete, "blah"),
    (ChangeTag::Insert, "blurgh"),
]);
