edit-distance

Calculate Levenshtein distance between two strings.

The Levenshtein edit distance is a measure for the similarity between two strings. It's helpful for spelling correction, fuzzy completion, type-ahead and similar use cases.

This implementation supports Unicode.

Installation

In Cargo.toml add

[dependencies]
edit-distance = "2.1.0"

Then re-run cargo build. That fetches the dependencies and builds the code.

Usage

extern crate edit_distance;

edit_distance("kitten", "sitting"); // => 3
