icu_properties crates.io

Definitions of Unicode Properties and APIs for retrieving property data in an appropriate data structure.

This module is published as its own crate (icu_properties) and as part of the icu crate. See the latter for more details on the ICU4X project.

APIs that return a CodePointSetData exist for binary properties and certain enumerated properties.

APIs that return a CodePointMapData exist for certain enumerated properties.

Examples

Property data as CodePointSetDatas

use icu::properties::{CodePointSetData, CodePointMapData};
use icu::properties::props::{GeneralCategory, Emoji};

// A binary property as a `CodePointSetData`

assert!(CodePointSetData::new::<Emoji>().contains('🎃')); // U+1F383 JACK-O-LANTERN
assert!(!CodePointSetData::new::<Emoji>().contains('')); // U+6728

// An individual enumerated property value as a `CodePointSetData`

let line_sep_data = CodePointMapData::<GeneralCategory>::new()
    .get_set_for_value(GeneralCategory::LineSeparator);
let line_sep = line_sep_data.as_borrowed();

assert!(line_sep.contains('\u{2028}'));
assert!(!line_sep.contains('\u{2029}'));

Property data as CodePointMapDatas

use icu::properties::CodePointMapData;
use icu::properties::props::Script;

assert_eq!(CodePointMapData::<Script>::new().get('🎃'), Script::Common); // U+1F383 JACK-O-LANTERN
assert_eq!(CodePointMapData::<Script>::new().get(''), Script::Han); // U+6728
