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. See the [sets] module for more details.
APIs that return a [CodePointMapData] exist for certain enumerated properties. See the
[maps] module for more details.
CodePointSetDatas```rust use icu::properties::{maps, sets, GeneralCategory};
// A binary property as a CodePointSetData
let data = sets::loademoji(&icutestdata::unstable()) .expect("The data should be valid"); let emoji = data.as_borrowed();
assert!(emoji.contains('🎃')); // U+1F383 JACK-O-LANTERN assert!(!emoji.contains('木')); // U+6728
// An individual enumerated property value as a CodePointSetData
let data = maps::loadgeneralcategory(&icutestdata::unstable()) .expect("The data should be valid"); let gc = data.asborrowed(); let linesepdata = gc.getsetforvalue(GeneralCategory::LineSeparator); let linesep = linesepdata.as_borrowed();
assert!(linesep.contains32(0x2028)); assert!(!linesep.contains32(0x2029)); ```
CodePointMapDatas```rust use icu::properties::{maps, Script};
let map = maps::loadscript(&icutestdata::unstable()) .expect("The data should be valid"); let script = map.as_borrowed();
asserteq!(script.get('🎃'), Script::Common); // U+1F383 JACK-O-LANTERN asserteq!(script.get('木'), Script::Han); // U+6728 ```
