Port of Python's difflib library to Rust
Port of Python's difflib library to Rust. It's provide all necessary tools for comparing word sequences.
Simply add difflib to your dependencies block in Cargo.toml
[dependencies]
difflib = "0.4.0"
Documentation is available at https://github.com/DimaKudosh/difflib/wiki
