Enum icu_datetime::fields::Weekday

#[repr(u8)]
pub enum Weekday {
    Format = 0,
    Local = 1,
    StandAlone = 2,
}

An enum for the possible symbols of a weekday field in a date pattern.

Variants

Format = 0

Field symbol for day of week (text format only).

This field symbol is represented by the character E in a date formatting pattern string.

For more details, see documentation on date field symbols.

Local = 1

Field symbol for day of week; numeric formats produce a locale-dependent ordinal weekday number.

For example, in de-DE, Monday is the 1st day of the week.

This field symbol is represented by the character e in a date formatting pattern string.

For more details, see documentation on date field symbols.

StandAlone = 2

Field symbol for stand-alone local day of week number/name.

The stand-alone weekday name is used when the weekday is displayed by itself. This may differ from the standard form based on the language and context.

This field symbol is represented by the character c in a date formatting pattern string.

For more details, see documentation on date field symbols.

Implementations

impl Weekday

pub(crate) fn new_from_u8(value: u8) -> Option<Self>

Attempt to construct the value from its corresponding integer, returning None if not possible

impl Weekday

pub(crate) fn idx(self) -> u8

Retrieves an index of the field variant.

Examples

use icu::datetime::fields::Month;

assert_eq!(Month::StandAlone::idx(), 1);

Stability

This is mostly useful for serialization, and does not guarantee index stability between ICU4X versions.

pub(crate) fn from_idx(idx: u8) -> Result<Self, SymbolError>

Retrieves a field variant from an index.

Examples

use icu::datetime::fields::Month;

assert_eq!(Month::from_idx(0), Month::Format);

Stability

This is mostly useful for serialization, and does not guarantee index stability between ICU4X versions.

Trait Implementations

impl AsULE for Weekday

type ULE = WeekdayULE

The ULE type corresponding to Self.

fn to_unaligned(self) -> Self::ULE

Converts from Self to Self::ULE.

fn from_unaligned(other: Self::ULE) -> Self

Converts from Self::ULE to Self.

impl Clone for Weekday

fn clone(&self) -> Weekday

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Weekday

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

Formats the value using the given formatter.

impl From<Weekday> for FieldSymbol

fn from(input: Weekday) -> Self

Converts to this type from the input type.

impl From<Weekday> for char

fn from(input: Weekday) -> char

Converts to this type from the input type.

impl Ord for Weekday

fn cmp(&self, other: &Weekday) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Weekday

fn eq(&self, other: &Weekday) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Weekday

fn partial_cmp(&self, other: &Weekday) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<char> for Weekday

type Error = SymbolError

The type returned in the event of a conversion error.

fn try_from(ch: char) -> Result<Self, Self::Error>

Performs the conversion.

impl<'a> Yokeable<'a> for Weekday

where Self: Sized,

type Output = Weekday

This type MUST be Self with the 'static replaced with 'a, i.e. Self<'a>

fn transform(&self) -> &Self::Output

This method must cast self between &'a Self<'static> and &'a Self<'a>.

fn transform_owned(self) -> Self::Output

This method must cast self between Self<'static> and Self<'a>.

unsafe fn make(this: Self::Output) -> Self

This method can be used to cast away Self<'a>’s lifetime.

fn transform_mut<F>(&'a mut self, f: F)

where F: 'static + for<'b> FnOnce(&'b mut Self::Output),

This method must cast self between &'a mut Self<'static> and &'a mut Self<'a>, and pass it to f.

impl<'zf> ZeroFrom<'zf, Weekday> for Weekday

fn zero_from(this: &'zf Self) -> Self

Clone the other C into a struct that may retain references into C.

impl<'a> ZeroMapKV<'a> for Weekday

type Container = ZeroVec<'a, Weekday>

The container that can be used with this type: ZeroVec or VarZeroVec.

type Slice = ZeroSlice<Weekday>

type GetType = WeekdayULE

The type produced by Container::get()

type OwnedType = Weekday

The type produced by Container::replace() and Container::remove(), also used during deserialization. If Self is human readable serialized, deserializing to Self::OwnedType should produce the same value once passed through Self::owned_as_self()
