diff.rs

An LCS based slice and string diffing implementation.

Example

``` extern crate diff;

fn main() { let left = "foo\nbar\nbaz\nquux"; let right = "foo\nbaz\nbar\nquux";

for diff in diff::lines(left, right) {
    match diff {
        diff::Result::Left(l)    => println!("-{}", l),
        diff::Result::Both(l, _) => println!(" {}", l),
        diff::Result::Right(r)   => println!("+{}", r)
    }
}

} ```

prints

foo +baz bar -baz quux
