Struct 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> Clone for DecompositionSupplementV1<'data>

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

Returns a duplicate 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<'data> PartialEq for DecompositionSupplementV1<'data>

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

Tests for self and other values to be equal, and is used by ==.

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

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

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.

impl<'data> StructuralPartialEq for DecompositionSupplementV1<'data>

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
