Struct NumericType 

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

Enumerated property Numeric_Type.

See Section 4.6, Numeric Value in The Unicode Standard for the summary of each property value.

Example

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

assert_eq!(
    CodePointMapData::<NumericType>::new().get('0'),
    NumericType::Decimal,
); // U+0030
assert_eq!(
    CodePointMapData::<NumericType>::new().get('½'),
    NumericType::Numeric,
); // U+00BD

Implementations

impl NumericType

pub const fn to_icu4c_value(self) -> u8

Returns an ICU4C UNumericType value.

pub const fn from_icu4c_value(value: u8) -> Self

Constructor from an ICU4C UNumericType value.

impl NumericType

pub const None: NumericType

Characters without numeric value

pub const Decimal: NumericType

(De) Characters of positional decimal systems

These are coextensive with GeneralCategory::DecimalNumber.

pub const Digit: NumericType

(Di) Variants of positional or sequences thereof.

The distinction between NumericType::Digit and NumericType::Numeric has not proven to be useful, so no further characters will be added to this type.

pub const Numeric: NumericType

(Nu) Other characters with numeric value

pub const ALL_VALUES: &'static [NumericType]

All possible values of this enum in the Unicode version from this ICU4X release.

Trait Implementations

impl AsULE for NumericType

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 NumericType

fn clone(&self) -> NumericType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NumericType

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

Formats the value using the given formatter.

impl EnumeratedProperty for NumericType

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<NumericType> for u16

fn from(other: NumericType) -> Self

Converts to this type from the input type.

impl Hash for NumericType

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 NumericType

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 NumericType

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

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

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

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.
