Enum icu::datetime::fieldset::dynamic::DateFieldSet

#[non_exhaustive]
pub enum DateFieldSet {
    D(D),
    MD(MD),
    YMD(YMD),
    DE(DE),
    MDE(MDE),
    YMDE(YMDE),
    E(E),
}

An enumeration over all possible date 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)

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.

D(D)

The day of the month, as in “on the 1st”.

MD(MD)

The month and day of the month, as in “January 1st”.

YMD(YMD)

The year, month, and day of the month, as in “January 1st, 2000”.

DE(DE)

The day of the month and day of the week, as in “Saturday 1st”.

MDE(MDE)

The month, day of the month, and day of the week, as in “Saturday, January 1st”.

YMDE(YMDE)

The year, month, day of the month, and day of the week, as in “Saturday, January 1st, 2000”.

E(E)

The day of the week alone, as in “Saturday”.

Implementations

impl DateFieldSet

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::DateFieldSet as FS;
use icu_provider::DataMarkerAttributes;

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

impl DateFieldSet

pub fn z(self) -> Combo<DateFieldSet, Zs>

Associates this field set with a specific non-location format time zone, as in “Pacific Daylight Time”.

pub fn o(self) -> Combo<DateFieldSet, O>

Associates this field set with an offset format time zone, as in “GMT−8”.

pub fn v(self) -> Combo<DateFieldSet, Vs>

Associates this field set with a generic non-location format time zone, as in “Pacific Time”.

pub fn l(self) -> Combo<DateFieldSet, L>

Associates this field set with a location format time zone, as in “Los Angeles time”.

Trait Implementations

impl Clone for DateFieldSet

fn clone(&self) -> DateFieldSet

Returns a copy of the value.

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

Performs copy-assignment from source.

impl DateDataMarkers for DateFieldSet

type Skel = FullDataCalMarkers

Cross-calendar data markers for date skeleta.

type Year = FullDataCalMarkers

Cross-calendar data markers for year names.

type Month = FullDataCalMarkers

Cross-calendar data markers for month names.

type WeekdayNamesV1Marker = WeekdayNamesV1Marker

Marker for loading weekday names.

impl DateInputMarkers for DateFieldSet

type YearInput = YearInfo

Marker for resolving the year input field.

type MonthInput = MonthInfo

Marker for resolving the month input field.

type DayOfMonthInput = DayOfMonth

Marker for resolving the day-of-month input field.

type DayOfYearInput = DayOfYearInfo

Marker for resolving the day-of-year input field.

type DayOfWeekInput = IsoWeekday

Marker for resolving the day-of-week input field.

impl DateTimeMarkers for DateFieldSet

impl PartialEq for DateFieldSet

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

Tests for self and other values to be equal, and is used by ==.

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

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