Struct icu::normalizer::properties::CanonicalCombiningClassMap

pub struct CanonicalCombiningClassMap { /* private fields */ }

Lookup of the Canonical_Combining_Class Unicode property.

Example

use icu_properties::CanonicalCombiningClass;
use icu_normalizer::properties::CanonicalCombiningClassMap;

let map = CanonicalCombiningClassMap::try_new_unstable(&icu_testdata::unstable()).unwrap();
assert_eq!(map.get('a'), CanonicalCombiningClass::NotReordered); // U+0061: LATIN SMALL LETTER A
assert_eq!(map.get32(0x0301), CanonicalCombiningClass::Above); // U+0301: COMBINING ACUTE ACCENT

Implementations

impl CanonicalCombiningClassMap

pub fn get(&self, c: char) -> CanonicalCombiningClass

Look up the canonical combining class for a scalar value

pub fn get32(&self, c: u32) -> CanonicalCombiningClass

Look up the canonical combining class for a scalar value represented as u32. If the argument is outside the scalar value range, CanonicalCombiningClass::NotReordered is returned.

pub fn try_new_unstable<D>(
    data_provider: &D
) -> Result<CanonicalCombiningClassMap, NormalizerError> where
    D: DataProvider<CanonicalDecompositionDataV1Marker> + ?Sized, 

Construct from data provider.

pub fn try_new_with_any_provider(
    provider: &impl AnyProvider
) -> Result<CanonicalCombiningClassMap, NormalizerError>

Creates a new instance using an AnyProvider.
