A Unicode First Day Identifier defines the preferred first day of the week for calendar display.

Specifying “fw” in a locale identifier overrides the default value specified by supplemental week data for the region.

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.

Implementations

impl FirstDay

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

A helper function for displaying as a &str.

Trait Implementations

impl Clone for FirstDay

fn clone(&self) -> FirstDay

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FirstDay

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

Formats the value using the given formatter.

impl From<FirstDay> for Value

fn from(input: FirstDay) -> Value

Converts to this type from the input type.

impl Hash for FirstDay

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 FirstDay

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

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<FirstDay>, 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 FirstDay

type Error = PreferencesParseError

The type returned in the event of a conversion error.

fn try_from(s: &Value) -> Result<FirstDay, <FirstDay as TryFrom<&Value>>::Error>

Performs the conversion.
