lev_distance

A copy of Levenshtein distance implementation from Rust Compiler.

This package uses String instead of Symbol of the Rust Compiler for general usage.

Example

use lev_distance::find_best_match_for_name;

fn main() {
    let v = vec!["aaa", "bbb"];
    let lookup = "aa";
    
    if let Some(sugg) = match find_best_match_for_name(v.iter(), "aa", None) {
        Some(sugg) if sugg == lookup => None,
        sugg => sugg,
    } {
        println!("Did you mean `{}`?", sugg);
    }
}

$ cargo run
Did you mean `aaa`?
