Struct BidiClass 

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

Enumerated property Bidi_Class

These are the categories required by the Unicode Bidirectional Algorithm. For the property values, see Bidirectional Class Values. For more information, see Unicode Standard Annex #9.

Example

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

assert_eq!(
    CodePointMapData::<BidiClass>::new().get('y'),
    BidiClass::LeftToRight
); // U+0079
assert_eq!(
    CodePointMapData::<BidiClass>::new().get('ع'),
    BidiClass::ArabicLetter
); // U+0639

Trait Implementations

impl AsULE for BidiClass

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 BidiClass

fn clone(&self) -> BidiClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BidiClass

impl Debug for BidiClass

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

impl Default for BidiClass

fn default() -> Self

Returns the “default value” for a type.

impl EnumeratedProperty for BidiClass

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 BidiClass

impl From<BidiClass> for u16

fn from(other: BidiClass) -> Self

Converts to this type from the input type.

impl Hash for BidiClass

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 BidiClass

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 BidiClass

fn cmp(&self, other: &BidiClass) -> 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 BidiClass

impl PartialEq for BidiClass

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for BidiClass

fn partial_cmp(&self, other: &BidiClass) -> 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 StructuralPartialEq for BidiClass

impl TrieValue for BidiClass

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.
