Struct icu_properties::bidi::BidiClassAdapter

pub struct BidiClassAdapter<'a> {
    data: CodePointMapDataBorrowed<'a, BidiClass>,
}

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);

Fields

data: CodePointMapDataBorrowed<'a, BidiClass>

Implementations

impl<'a> BidiClassAdapter<'a>

pub const fn new( data: CodePointMapDataBorrowed<'a, BidiClass>, ) -> BidiClassAdapter<'a>

Creates new instance of BidiClassAdapter.

Trait Implementations

impl<'a> BidiDataSource for BidiClassAdapter<'a>

fn bidi_class(&self, c: char) -> DataSourceBidiClass

Returns a DataSourceBidiClass given a unicode character.

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);

fn bidi_matched_opening_bracket( &self, c: char, ) -> Option<BidiMatchedOpeningBracket>

If this character is a bracket according to BidiBrackets.txt, return the corresponding normalized opening bracket of the pair, and whether or not it itself is an opening bracket.
