Struct icu::normalizer::provider::DecompositionSupplementV1

pub struct DecompositionSupplementV1<'data> {
    pub trie: CodePointTrie<'data, u32>,
    pub flags: u8,
    pub passthrough_cap: u16,
}

Data that either NFKD or the decomposed form of UTS 46 needs in addition to the NFD data.

Fields

trie: CodePointTrie<'data, u32>

Trie for the decompositions that differ from NFD. Getting a zero from this trie means that you need to make another lookup from DecompositionDataV1::trie.

flags: u8

Flags that indicate how the set of characters whose decompositions starts with a non-starter differs from the set for NFD.

Bit 0: Whether half-width kana voicing marks decompose into non-starters (their full-width combining counterparts). Bit 1: Whether U+0345 COMBINING GREEK YPOGEGRAMMENI decomposes into a starter (U+03B9 GREEK SMALL LETTER IOTA). (Other bits unused.)

passthrough_cap: u16

The passthrough bounds of NFD/NFC are lowered to this maximum instead. (16-bit, because cannot be higher than 0x0300, which is the bound for NFC.)

Implementations

impl<'_> DecompositionSupplementV1<'_>

pub fn half_width_voicing_marks_become_non_starters(&self) -> bool
