Struct GraphemeClusterBreak 

pub struct GraphemeClusterBreak(/* private fields */);

Enumerated property Grapheme_Cluster_Break.

See “Default Grapheme Cluster Boundary Specification” in UAX #29 for the summary of each property value: https://www.unicode.org/reports/tr29/#Default_Grapheme_Cluster_Table

Note: Use icu::segmenter for an all-in-one break iterator implementation.

Example

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

assert_eq!(
    CodePointMapData::<GraphemeClusterBreak>::new().get('🇦'),
    GraphemeClusterBreak::RegionalIndicator
); // U+1F1E6: Regional Indicator Symbol Letter A
assert_eq!(
    CodePointMapData::<GraphemeClusterBreak>::new().get('ำ'),
    GraphemeClusterBreak::SpacingMark
); //U+0E33: Thai Character Sara Am

Trait Implementations

impl AsULE for GraphemeClusterBreak

type ULE = u8

The ULE type corresponding to Self.

fn to_unaligned(self) -> Self::ULE

Converts from Self to Self::ULE.

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

Converts from Self::ULE to Self.

impl Clone for GraphemeClusterBreak

fn clone(&self) -> GraphemeClusterBreak

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GraphemeClusterBreak

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

Formats the value using the given formatter.

impl EnumeratedProperty for GraphemeClusterBreak

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 From<GraphemeClusterBreak> for u16

fn from(other: GraphemeClusterBreak) -> Self

Converts to this type from the input type.

impl Hash for GraphemeClusterBreak

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 NamedEnumeratedProperty for GraphemeClusterBreak

fn try_from_str(s: &str) -> Option<Self>

Convenience method for PropertyParser::new().get_loose(s)

fn long_name(&self) -> &'static str

Convenience method for PropertyNamesLong::new().get(*self).unwrap()

fn short_name(&self) -> &'static str

Convenience method for PropertyNamesShort::new().get(*self).unwrap()

impl Ord for GraphemeClusterBreak

fn cmp(&self, other: &GraphemeClusterBreak) -> 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 PartialEq for GraphemeClusterBreak

fn eq(&self, other: &GraphemeClusterBreak) -> 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 PartialOrd for GraphemeClusterBreak

fn partial_cmp(&self, other: &GraphemeClusterBreak) -> 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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl TrieValue for GraphemeClusterBreak

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.

impl Copy for GraphemeClusterBreak

impl Eq for GraphemeClusterBreak

impl ParseableEnumeratedProperty for GraphemeClusterBreak

impl StructuralPartialEq for GraphemeClusterBreak

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.
