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<BidiClass> for u16

fn from(other: BidiClass) -> Self

Converts to this type from the input type.

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,

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 PartialEq for BidiClass

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

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.
