Enum icu_datetime::fields::Month

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

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

Variants§

§

Format = 0

Field symbol for month number or name in a pattern that contains multiple fields.

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

For more details, see documentation on date field symbols.

§

StandAlone = 1

Field symbol for a “stand-alone” month number or name.

The stand-alone month name is used when the month 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 L in a date formatting pattern string.

For more details, see documentation on date field symbols.

Implementations§

source§

impl Month

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 Month

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.
