Enum MeasurementUnitOverride

#[non_exhaustive]
pub enum MeasurementUnitOverride {
    Celsius,
    Kelvin,
    Fahrenheit,
}

A Measurement Unit Preference Override defines an override for measurement unit preference.

The valid values are listed in LDML.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Celsius

Celsius as temperature unit

Kelvin

Kelvin as temperature unit

Fahrenheit

Fahrenheit as temperature unit

Implementations

impl MeasurementUnitOverride

pub const fn as_str(&self) -> &'static str

A helper function for displaying as a &str.

Trait Implementations

impl Clone for MeasurementUnitOverride

fn clone(&self) -> MeasurementUnitOverride

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MeasurementUnitOverride

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

Formats the value using the given formatter.

impl From<MeasurementUnitOverride> for Value

fn from(input: MeasurementUnitOverride) -> Value

Converts to this type from the input type.

impl Hash for MeasurementUnitOverride

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 PartialEq for MeasurementUnitOverride

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

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<Self>, 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 MeasurementUnitOverride

type Error = PreferencesParseError

The type returned in the event of a conversion error.

fn try_from(s: &Value) -> Result<Self, Self::Error>

Performs the conversion.
