Enum icu_datetime::fields::Weekday

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

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§

source§

impl Weekday

source

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

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

source§

impl Weekday

source

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.

source

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.
