Struct Age

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

Represents values of the Unicode character property Age.

The Age property indicates the age of a character, which is defined based on the first Unicode version in which a particular Unicode character was assigned (as character or noncharacter).

Note: Age type has a reverse ordering compared to UnicodeVersion, because a character is older (has greater age) of another character if, and only if, it has a older (smaller) UnicodeVersion number.

Unicode versions with character assignement always have the Micro (Update) version value of zero (0). Therefore, all UnicodeVersion values return from Age will have their macro field as 0.

The earliest (largest) value for this property is UnicodeVersion { major: 1, minor: 1, micro: 0 }, because of the massive changes for the merger of the Unicode Standard with ISO 10646.

The latest (smallest) value for this property is always equal to or greater than UNICODE_VERSION. (Only not equal when UNICODE_VERSION has non-zero micro value.)

Implementations

impl Age

pub fn of(ch: char) -> Option<Age>

Return the UnicodeVersion value of the age.

Trait Implementations

impl CharProperty for Age

fn prop_abbr_name() -> &'static str

The abbreviated name of the property.

fn prop_long_name() -> &'static str

The long name of the property.

fn prop_human_name() -> &'static str

The human-readable name of the property.

impl Clone for Age

fn clone(&self) -> Age

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CustomCharProperty<UnicodeVersion> for Age

fn actual(&self) -> UnicodeVersion

Get numeric value for character property value

impl Debug for Age

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

Formats the value using the given formatter.

impl Hash for Age

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 Age

fn cmp(&self, other: &Age) -> 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 PartialCharProperty for Age

fn of(ch: char) -> Option<Self>

The property value for the character, or None.

impl PartialEq for Age

fn eq(&self, other: &Age) -> 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 Age

fn partial_cmp(&self, other: &Age) -> 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.
