Implementations

impl Database

Database

pub fn get_distance(&self, from: &str, to: &str) -> u8

Get the matching rate of character. Range is 0..galm::Database.max_distance_size. The more similar the two arguments, the smaller the return value.

// Initialize GalM Database instance.
let galm: galm::Database = galm::Database::default();

// Get the matching rate of character.
let distance: u8 = galm.get_distance("王", "玉");

assert_eq!(distance, 22);

pub fn get_word_distance(&self, str1: &str, str2: &str) -> usize

Get the matching rate of word. Range is 0..std::usize::MAX. The more similar the two arguments, the smaller the return value.

// Initialize GalM Database instance.
let galm: galm::Database = galm::Database::default();

let sort_key = "王様";
let mut vec = ["皇様", "玉様", "大様"];

// Sort Example
vec.sort_by_key( |candidate| galm.get_word_distance(sort_key, candidate) );

assert_eq!(vec, ["玉様", "大様", "皇様"]);
