Function similar::utils::diff_words[−][src]

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

Shortcut for making a word level diff.

This function produces the diff of two strings and returns a vector with the changes. It returns connected slices into the original string rather than word level slices.

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

assert_eq!(diff_words(Algorithm::Myers, "foo bar baz", "foo bor baz"), vec![
    (ChangeTag::Equal, "foo "),
    (ChangeTag::Delete, "bar"),
    (ChangeTag::Insert, "bor"),
    (ChangeTag::Equal, " baz"),
]);
