Struct icu::locale::preferences::extensions::unicode::keywords::NumberingSystem

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

A Unicode Number System Identifier defines a type of number system.

The valid values are listed in LDML.

Methods from Deref<Target = Subtag>

pub fn as_str(&self) -> &str

A helper function for displaying as a &str.

pub fn to_string(&self) -> String

Converts the given value to a String.

Under the hood, this uses an efficient [Writeable] implementation. However, in order to avoid allocating a string, it is more efficient to use [Writeable] directly.

pub fn len(&self) -> usize

Returns the length of self.

Examples

use icu::locale::subtags::subtag;
let s = subtag!("foo");
assert_eq!(s.len(), 3);

Trait Implementations

impl Clone for NumberingSystem

fn clone(&self) -> NumberingSystem

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NumberingSystem

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

Formats the value using the given formatter.

impl Deref for NumberingSystem

type Target = Subtag

The resulting type after dereferencing.

fn deref(&self) -> &<NumberingSystem as Deref>::Target

Dereferences the value.

impl From<NumberingSystem> for Value

fn from(input: NumberingSystem) -> Value

Converts to this type from the input type.

impl Hash for NumberingSystem

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 PartialEq for NumberingSystem

fn eq(&self, other: &NumberingSystem) -> 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 PreferenceKey for NumberingSystem

fn unicode_extension_key() -> Option<Key>

Retrieve unicode extension key corresponding to a given preference.

fn try_from_key_value( key: &Key, value: &Value, ) -> Result<Option<NumberingSystem>, PreferencesParseError>

Optional constructor of the given preference. It takes the unicode extension key and if the key matches it attemptes to construct the preference based on the given value. If the value is not a valid value for the given key, the constructor throws.

fn unicode_extension_value(&self) -> Option<Value>

Retrieve unicode extension value corresponding to the given instance of the preference.

impl TryFrom<Value> for NumberingSystem

type Error = PreferencesParseError

The type returned in the event of a conversion error.

fn try_from( input: Value, ) -> Result<NumberingSystem, <NumberingSystem as TryFrom<Value>>::Error>

Performs the conversion.
