Struct E

#[non_exhaustive]
pub struct E {
    pub length: Length,
}

“Friday” ⇒ weekday (standalone)

This is a field set marker. For more information, see fieldsets.

Examples

In DateTimeFormatter:

use icu::datetime::input::Date;
use icu::datetime::DateTimeFormatter;
use icu::datetime::fieldsets::E;
use icu::locale::locale;
use writeable::assert_writeable_eq;
let fmt = DateTimeFormatter::<E>::try_new(
    locale!("en").into(),
   E::long(),
)
.unwrap();
let dt = Date::try_new_iso(2024, 5, 17).unwrap();

assert_writeable_eq!(
    fmt.format(&dt),
   "Friday"
);

In FixedCalendarDateTimeFormatter:

use icu::datetime::input::Date;
use icu::calendar::Gregorian;
use icu::datetime::FixedCalendarDateTimeFormatter;
use icu::datetime::fieldsets::E;
use icu::locale::locale;
use writeable::assert_writeable_eq;

let fmt = FixedCalendarDateTimeFormatter::<Gregorian, E>::try_new(
    locale!("en").into(),
   E::long(),
)
.unwrap();
let dt = Date::try_new_gregorian(2024, 5, 17).unwrap();

assert_writeable_eq!(
    fmt.format(&dt),
   "Friday"
);

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

length: Length

The desired length of the formatted string.

See: Length

Implementations

impl E

pub const fn with_length(length: Length) -> Self

Creates a E skeleton with the given formatting length.

pub const fn long() -> Self

Creates a E skeleton with a long length.

pub const fn medium() -> Self

Creates a E skeleton with a medium length.

pub const fn short() -> Self

Creates a E skeleton with a short length.

impl E

pub fn zone<Z: ZoneMarkers>(self, zone: Z) -> Combo<Self, Z>

Associates this field set with a time zone field set.

Trait Implementations

impl Clone for E

fn clone(&self) -> E

Returns a copy of the value.

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

Performs copy-assignment from source.

impl DateDataMarkers for E

type Skel = FullDataCalMarkers

Cross-calendar data markers for date skeleta.

type Year = NoDataCalMarkers

Cross-calendar data markers for year names.

type Month = NoDataCalMarkers

Cross-calendar data markers for month names.

type WeekdayNamesV1 = WeekdayNamesV1

Marker for loading weekday names.

impl DateInputMarkers for E

type YearInput = ()

Marker for resolving the year input field.

type MonthInput = ()

Marker for resolving the month input field.

type DayOfMonthInput = ()

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

type DayOfYearInput = ()

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

type DayOfWeekInput = Weekday

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

impl DateTimeMarkers for E

type D = E

Associated types for date formatting.

type T = ()

Associated types for time formatting.

type Z = ()

Associated types for time zone formatting.

type GluePatternV1 = NeverMarker<GluePattern<'static>>

Marker for loading the date/time glue pattern.

impl DateTimeNamesMarker for E

type YearNames = ()

type MonthNames = ()

type WeekdayNames = WeekdayNamesV1

type DayPeriodNames = ()

type ZoneEssentials = ()

type ZoneLocations = ()

type ZoneLocationsRoot = ()

impl Debug for E

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

Formats the value using the given formatter.

impl GetField<CompositeFieldSet> for E

fn get_field(&self) -> CompositeFieldSet

Returns the value of this trait’s field T.

impl PartialEq for E

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

type DateSkeletonPatternsV1 = <C as CldrCalendar>::SkeletaV1

Marker for loading date skeleton patterns.

type YearNamesV1 = NeverMarker<YearNames<'static>>

Marker for loading year names.

type MonthNamesV1 = NeverMarker<MonthNames<'static>>

Marker for loading month names.
