Struct icu_properties::bidi::BidiClassAdapter

source ·
pub struct BidiClassAdapter<'a> {
    data: CodePointMapDataBorrowed<'a, BidiClass>,
}
Expand description

An adapter to convert from icu4x BidiClass to unicode_bidi::BidiClass.

Enabled with the bidi Cargo feature.

§Example

use icu::collections::codepointtrie::CodePointTrie;
use icu::properties::bidi::BidiClassAdapter;
use icu::properties::{maps, BidiClass};
use unicode_bidi::BidiClass as DataSourceBidiClass;
use unicode_bidi::BidiDataSource;

let adapter = BidiClassAdapter::new(maps::bidi_class());
assert_eq!(adapter.bidi_class('a'), DataSourceBidiClass::L);
assert_eq!(adapter.bidi_class('ع'), DataSourceBidiClass::AL);
