Enum icu_datetime::fields::symbols::Day

#[repr(u8)]
pub enum Day { DayOfMonth = 0, DayOfYear = 1, DayOfWeekInMonth = 2, ModifiedJulianDay = 3, }
Expand description

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

Variants§

§

DayOfMonth = 0

Field symbol for day of month (numeric).

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

For more details, see documentation on date field symbols.

§

DayOfYear = 1

Field symbol for day of year (numeric).

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

For more details, see documentation on date field symbols.

§

DayOfWeekInMonth = 2

Field symbol for the day of week occurrence relative to the month (numeric).

For the example "2nd Wed in July", this field would provide "2". Should likely be paired with the Weekday field.

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

For more details, see documentation on date field symbols.

§

ModifiedJulianDay = 3

Field symbol for the modified Julian day (numeric).

The value of this field differs from the conventional Julian day number in a couple of ways, which are based on measuring relative to the local time zone.

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

For more details, see documentation on date field symbols.

Implementations§

source§

impl Day

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 Day

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.
