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.

🚧 This code is considered unstable; it may change at any time, in breaking or non-breaking ways, including in SemVer minor releases. While the serde representation of data structs is guaranteed to be stable, their Rust representation might not be. Use with caution.

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

Whether half-width kana voicing marks decompose into non-starters (their full-width combining counterparts).

Trait Implementations

impl<'data> Bake for DecompositionSupplementV1<'data>

fn bake(&self, env: &CrateEnv) -> TokenStream

Returns a TokenStream that would evaluate to self.

impl<'data> Clone for DecompositionSupplementV1<'data>

fn clone(&self) -> DecompositionSupplementV1<'data>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'data> Debug for DecompositionSupplementV1<'data>

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

Formats the value using the given formatter.

impl<'de: 'data, 'data> Deserialize<'de> for DecompositionSupplementV1<'data>

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'data> PartialEq<DecompositionSupplementV1<'data>> for DecompositionSupplementV1<'data>

fn eq(&self, other: &DecompositionSupplementV1<'data>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'data> Serialize for DecompositionSupplementV1<'data>

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<'a> Yokeable<'a> for DecompositionSupplementV1<'static>

type Output = DecompositionSupplementV1<'a>

This type MUST be Self with the 'static replaced with 'a, i.e. Self<'a>

fn transform(&'a self) -> &'a Self::Output

This method must cast self between &'a Self<'static> and &'a Self<'a>.

fn transform_owned(self) -> Self::Output

This method must cast self between Self<'static> and Self<'a>.

unsafe fn make(this: Self::Output) -> Self

This method can be used to cast away Self<'a>’s lifetime.

fn transform_mut<F>(&'a mut self, f: F)where F: 'static + for<'b> FnOnce(&'b mut Self::Output),

This method must cast self between &'a mut Self<'static> and &'a mut Self<'a>, and pass it to f.

impl<'zf, 'zf_inner> ZeroFrom<'zf, DecompositionSupplementV1<'zf_inner>> for DecompositionSupplementV1<'zf>

fn zero_from(this: &'zf DecompositionSupplementV1<'zf_inner>) -> Self

Clone the other C into a struct that may retain references into C.
