Struct icu_normalizer::properties::CanonicalCombiningClassMap

pub struct CanonicalCombiningClassMap {
    decompositions: DataPayload<CanonicalDecompositionDataV1Marker>,
}

Lookup of the Canonical_Combining_Class Unicode property.

Example

use icu::properties::CanonicalCombiningClass;
use icu::normalizer::properties::CanonicalCombiningClassMap;

let map = CanonicalCombiningClassMap::new();
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

Fields

decompositions: DataPayload<CanonicalDecompositionDataV1Marker>

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 const fn new() -> Self

Construct from compiled data.

✨ Enabled with the compiled_data Cargo feature.
