Struct icu::datetime::fieldsets::D

#[non_exhaustive]
pub struct D {
    pub length: Length,
    pub alignment: Option<Alignment>,
}

“17” ⇒ day of month (standalone)

Examples

In DateTimeFormatter:

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

assert_writeable_eq!(
    fmt.format_any_calendar(&dt),
   "17"
);

In FixedCalendarDateTimeFormatter:

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

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

assert_writeable_eq!(
    fmt.format(&dt),
   "17"
);

This format may use ordinal formatting, such as “the 17th”, in the future. See CLDR-18040.

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

alignment: Option<Alignment>

Whether fields should be aligned for a column-like layout.

See: Alignment

Implementations

impl D

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

Creates a D skeleton with the given formatting length.

impl D

pub const fn with_alignment(self, alignment: Alignment) -> D

Sets the alignment option.

impl D

pub fn zone_z(self) -> Combo<D, Zs>

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

pub fn zone_o(self) -> Combo<D, O>

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

pub fn zone_v(self) -> Combo<D, Vs>

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

pub fn zone_l(self) -> Combo<D, L>

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