Enumerated property General_Category.

General_Category specifies the most general classification of a code point, usually determined based on the primary characteristic of the assigned character. For example, is the character a letter, a mark, a number, punctuation, or a symbol, and if so, of what type?

GeneralCategory only supports specific subcategories (eg UppercaseLetter). It does not support grouped categories (eg Letter). For grouped categories, use GeneralCategoryGroup.

Trait Implementations

impl AsULE for GeneralCategory

type ULE = GeneralCategoryULE

The ULE type corresponding to Self.

fn to_unaligned(self) -> Self::ULE

Converts from Self to Self::ULE.

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

Converts from Self::ULE to Self.

impl Bake for GeneralCategory

fn bake(&self, env: &CrateEnv) -> TokenStream

Returns a TokenStream that would evaluate to self.

impl Clone for GeneralCategory

fn clone(&self) -> GeneralCategory

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GeneralCategory

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GeneralCategory

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<GeneralCategory> for GeneralCategoryGroup

fn from(subcategory: GeneralCategory) -> Self

Converts to this type from the input type.

impl Ord for GeneralCategory

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for GeneralCategory

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for GeneralCategory

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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.

type GetType = GeneralCategoryULE

The type produced by Container::get()

type OwnedType = GeneralCategory

The type produced by Container::replace() and Container::remove(), also used during deserialization. If Self is human readable serialized, deserializing to Self::OwnedType should produce the same value once passed through Self::owned_as_self()
