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.

[semantic cleanups]: https://neil.fraser.name/writing/diff/

```toml
[dependencies]
dissimilar = "1.0"
```

## Interface

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.

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

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

## License

The diff algorithm in this crate was ported to Rust using the Java and C++
implementations found at <https://github.com/google/diff-match-patch> as

project, including some parts unmodified from upstream and the Rust-specific
modifications introduced in the course of porting the implementation, are

Intellectual property that is unique to the Rust implementation is additionally
made available to you dually under the <a href="LICENSE-MIT">MIT license</a>, if
you prefer. This applies to all design choices and implementation choices not
