Enum icu_datetime::fieldset::dynamic::DateAndTimeFieldSet

#[non_exhaustive]
pub enum DateAndTimeFieldSet {
    DT(DT),
    MDT(MDT),
    YMDT(YMDT),
    DET(DET),
    MDET(MDET),
    YMDET(YMDET),
    ET(ET),
}

An enumeration over all possible date+time composite 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.

DT(DT)

The day of the month with time of day, as in “on the 1st at 10:31 AM”.

MDT(MDT)

The month and day of the month with time of day, as in “January 1st at 10:31 AM”.

YMDT(YMDT)

The year, month, and day of the month with time of day, as in “January 1st, 2000 at 10:31 AM”.

DET(DET)

The day of the month and day of the week with time of day, as in “Saturday 1st at 10:31 AM”.

MDET(MDET)

The month, day of the month, and day of the week with time of day, as in “Saturday, January 1st at 10:31 AM”.

YMDET(YMDET)

The year, month, day of the month, and day of the week with time of day, as in “Saturday, January 1st, 2000 at 10:31 AM”.

ET(ET)

The day of the week alone with time of day, as in “Saturday at 10:31 AM”.

Implementations

impl DateAndTimeFieldSet

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::DateAndTimeFieldSet as FS;
use icu_provider::DataMarkerAttributes;

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

impl DateAndTimeFieldSet

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

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

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

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

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

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

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

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

Trait Implementations

impl Clone for DateAndTimeFieldSet

fn clone(&self) -> DateAndTimeFieldSet

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DateAndTimeFieldSet

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl GetField<CompositeFieldSet> for DateAndTimeFieldSet

fn get_field(&self) -> CompositeFieldSet

Returns the value of this trait’s field T.

impl PartialEq for DateAndTimeFieldSet

fn eq(&self, other: &DateAndTimeFieldSet) -> 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.
