🚧 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>

Mapping from char to CollationElement32 (represented as its u32 bits).

ces: ZeroVec<'data, u64>

CollationElements used in expansions and offset CE32s (represented as their u64 bits)

ce32s: ZeroVec<'data, u32>

CollationElement32s used in expansions and as defaults for digits when the numeric mode is not in use

contexts: ZeroVec<'data, u16>

Defaults and tries for prefix and contraction matching

Trait Implementations

impl<'data> Clone for CollationDataV1<'data>

fn clone(&self) -> CollationDataV1<'data>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'data> Debug for CollationDataV1<'data>

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

Formats the value using the given formatter.

impl<'data> PartialEq for CollationDataV1<'data>

fn eq(&self, other: &CollationDataV1<'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 CollationDataV1<'static>

type Output = CollationDataV1<'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, CollationDataV1<'zf_inner>> for CollationDataV1<'zf>

fn zero_from(this: &'zf CollationDataV1<'zf_inner>) -> Self

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