Expand description

The raw (non-recursive) canonical decomposition operation.

Callers should generally use DecomposingNormalizer instead of this API. However, this API is provided for callers such as HarfBuzz that specifically want access to non-recursive canonical decomposition e.g. for use in a glyph-availability-guided custom normalizer.

Implementations§

source§

impl CanonicalDecomposition

source

pub fn decompose(&self, c: char) -> Decomposed

Performs non-recursive canonical decomposition (including for Hangul).

    use icu::normalizer::properties::Decomposed;
    let decomp = icu::normalizer::properties::CanonicalDecomposition::new();

    assert_eq!(decomp.decompose('e'), Decomposed::Default);
    assert_eq!(
        decomp.decompose('ệ'),
        Decomposed::Expansion('ẹ', '\u{0302}')
    );
    assert_eq!(decomp.decompose('각'), Decomposed::Expansion('가', 'ᆨ'));
    assert_eq!(decomp.decompose('\u{212B}'), Decomposed::Singleton('Å')); // ANGSTROM SIGN
    assert_eq!(decomp.decompose('\u{2126}'), Decomposed::Singleton('Ω')); // OHM SIGN
    assert_eq!(decomp.decompose('\u{1F71}'), Decomposed::Singleton('ά')); // oxia
source

fn decompose_non_hangul(&self, c: char) -> Decomposed

Performs non-recursive canonical decomposition except Hangul syllables are reported as Decomposed::Default.
