Struct icu_properties::bidi::BidiClassAdapter

pub struct BidiClassAdapter<'a> { /* private fields */ }

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

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 data = maps::load_bidi_class(&icu_testdata::unstable())
    .expect("The data should be valid");

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

Implementations

impl<'a> BidiClassAdapter<'a>

pub 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 data = maps::load_bidi_class(&icu_testdata::unstable())
    .expect("The data should be valid");

let adapter = BidiClassAdapter::new(data.as_borrowed());
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.

impl<'a> Debug for BidiClassAdapter<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result
