Enum icu::datetime::fieldset::dynamic::CalendarPeriodFieldSet

source ·
#[non_exhaustive]
pub enum CalendarPeriodFieldSet { M(M), YM(YM), Y(Y), }
Expand description

An enumeration over all possible calendar period field sets.

📏 Note: This enum can be used as the field set parameter of DateTimeFormatter, but doing so may link more formatting data compared to the individual field set structs.

Variants (Non-exhaustive)§

This enum is marked as 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.
§

M(M)

A standalone month, as in “January”.

§

YM(YM)

A month and year, as in “January 2000”.

§

Y(Y)

A year, as in “2000”.

Implementations§

source§

impl CalendarPeriodFieldSet

source

pub const ALL_DATA_MARKER_ATTRIBUTES: &'static [&'static DataMarkerAttributes] = _

All attributes associated with this enum.

§Encoding Details

The string is based roughly on the UTS 35 symbol table with the following exceptions:

  1. Lowercase letters are chosen where there is no ambiguity: E becomes e
  2. Capitals are replaced with their lowercase and a number 0: M becomes m0
  3. A single symbol is included for each component: length doesn’t matter
  4. Time fields are encoded with their hour field only: j, h, or h0
§Examples
use icu::datetime::fieldset::dynamic::CalendarPeriodFieldSet as FS;
use icu_provider::DataMarkerAttributes;

assert!(FS::ALL_DATA_MARKER_ATTRIBUTES.contains(
    &DataMarkerAttributes::from_str_or_panic("m0")
));
