This crate provides utilities around least common subsequences. From a least common subsequences table, you can also calculate diffs (see LcsTable::diff).

Usage of this crate is centered around LcsTable, so most interesting documentation can be found there.

lcs

A library for finding longest common substrings. You can also use this library to calculate a diff between two sequences.

Example

extern crate lcs;

let a: Vec<_> = "a--b---c".chars().collect();
let b: Vec<_> = "abc".chars().collect();

let table = lcs::LcsTable::new(&a, &b);
let lcs = table.longest_common_subsequence();

assert_eq!(vec![&'a', &'b', &'c'], lcs);
