Crate japanese_codepoints 

japanese-codepoints

A Rust library for validating and working with Japanese character code points based on JIS standards.

Character sets

Feature	Module	Description
(default)	—	ASCII control / printable via CodePoints
codepoints-jisx0201	[jisx0201]	Latin letters and halfwidth katakana
codepoints-jisx0208	[jisx0208]	Hiragana, katakana, Latin, Greek, Cyrillic, symbols
codepoints-jisx0208kanji	[jisx0208kanji]	6 355 kanji (JIS X 0208 Level 1 & 2)
codepoints-jisx0213kanji	[jisx0213kanji]	10 050 kanji (JIS X 0213 Level 1–4)
full	—	All of the above

Quick start

use japanese_codepoints::CodePoints;

let allowed = CodePoints::new(vec![0x3041, 0x3042]); // ぁ, あ
assert!(allowed.contains("あ"));
assert!(!allowed.contains("う"));

Multi-set validation

Use contains_all_in_any to check whether every character in a string belongs to at least one of several character sets:

use japanese_codepoints::{CodePoints, contains_all_in_any};

let hiragana = CodePoints::new(vec![0x3042, 0x3044]); // あ, い
let katakana = CodePoints::new(vec![0x30A2, 0x30A4]); // ア, イ
assert!(contains_all_in_any("あア", &[&hiragana, &katakana]));

For a version that returns a structured error, see validation::validate_all_in_any.
