Struct CanonicalCombiningClass 

#[repr(transparent)]
pub struct CanonicalCombiningClass(pub u8);

Property Canonical_Combining_Class. See UAX #15: https://www.unicode.org/reports/tr15/.

Note: See icu::normalizer::properties::CanonicalCombiningClassMap for the preferred API to look up the Canonical_Combining_Class property by scalar value.

Example

use icu::properties::{CodePointMapData, props::CanonicalCombiningClass};

assert_eq!(
    CodePointMapData::<CanonicalCombiningClass>::new().get('a'),
    CanonicalCombiningClass::NotReordered
); // U+0061: LATIN SMALL LETTER A
assert_eq!(
    CodePointMapData::<CanonicalCombiningClass>::new().get('\u{0301}'),
    CanonicalCombiningClass::Above
); // U+0301: COMBINING ACUTE ACCENT

Converts from Self to Self::ULE.

fn from_unaligned(unaligned: Self::ULE) -> Self

Converts from Self::ULE to Self.

impl Clone for CanonicalCombiningClass

fn clone(&self) -> CanonicalCombiningClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CanonicalCombiningClass

impl Debug for CanonicalCombiningClass

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

Formats the value using the given formatter.

impl Default for CanonicalCombiningClass

fn default() -> Self

Returns the “default value” for a type.

impl EnumeratedProperty for CanonicalCombiningClass

const NAME: &'static [u8]

The name of this property

const SHORT_NAME: &'static [u8]

The abbreviated name of this property, if it exists, otherwise the name

fn for_char(ch: char) -> Self

Convenience method for CodePointMapData::new().get(ch)

impl Eq for CanonicalCombiningClass

impl From<CanonicalCombiningClass> for u16

fn from(other: CanonicalCombiningClass) -> Self

Converts to this type from the input type.

impl Hash for CanonicalCombiningClass

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for CanonicalCombiningClass

fn cmp(&self, other: &CanonicalCombiningClass) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl ParseableEnumeratedProperty for CanonicalCombiningClass

impl PartialEq for CanonicalCombiningClass

fn eq(&self, other: &CanonicalCombiningClass) -> bool

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for CanonicalCombiningClass

fn partial_cmp(&self, other: &CanonicalCombiningClass) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

impl StructuralPartialEq for CanonicalCombiningClass

impl TrieValue for CanonicalCombiningClass

type TryFromU32Error = TryFromIntError

Last-resort fallback value to return if we cannot read data from the trie.

fn try_from_u32(i: u32) -> Result<Self, Self::TryFromU32Error>

A parsing function that is primarily motivated by deserialization contexts. When the serialization type width is smaller than 32 bits, then it is expected that the call site will widen the value to a u32 first.

fn to_u32(self) -> u32

A method for converting back to a u32 that can roundtrip through Self::try_from_u32(). The default implementation of this trait method panics in debug mode and returns 0 in release mode.
