§Diff library with semantic cleanup, based on Google’s diff-match-patch

This library is a port of the Diff component of Diff Match Patch to Rust. The diff implementation is based on Myers’ diff algorithm but includes some semantic cleanups to increase human readability by factoring out commonalities which are likely to be coincidental.

Diff Match Patch was originally built in 2006 to power Google Docs.


Here is the entire API of the Rust implementation. It operates on borrowed strings and the return value of the diff algorithm is a vector of chunks pointing into slices of those input strings.

pub enum Chunk<'a> {
    Equal(&'a str),
    Delete(&'a str),
    Insert(&'a str),

pub fn diff(text1: &str, text2: &str) -> Vec<Chunk>;
