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

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

A Region Override specifies an alternate region to use for obtaining certain region-specific default values.

The valid values are listed in LDML.

Methods from Deref<Target = SubdivisionId>

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.

Trait Implementations

impl Clone for RegionOverride

fn clone(&self) -> RegionOverride

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RegionOverride

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

Formats the value using the given formatter.

impl Deref for RegionOverride

type Target = SubdivisionId

The resulting type after dereferencing.

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

Dereferences the value.

impl From<RegionOverride> for Value

fn from(input: RegionOverride) -> Value

Converts to this type from the input type.

impl Hash for RegionOverride

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 RegionOverride

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

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<RegionOverride>, 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 RegionOverride

type Error = PreferencesParseError

The type returned in the event of a conversion error.

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

Performs the conversion.
