Struct icu::datetime::fieldset::DE

source ·
#[non_exhaustive]
pub struct DE { pub length: NeoSkeletonLength, pub alignment: Option<Alignment>, }
Expand description

“17 Friday” ⇒ day of month and weekday

§Examples

In DateTimeFormatter:

use icu::calendar::Date;
use icu::datetime::DateTimeFormatter;
use icu::datetime::fieldset::DE;
use icu::locale::locale;
use writeable::assert_try_writeable_eq;
let fmt = DateTimeFormatter::<DE>::try_new(
    &locale!("en").into(),
   DE::long(),
)
.unwrap();
let dt = Date::try_new_iso(2024, 5, 17).unwrap();

assert_try_writeable_eq!(
    fmt.convert_and_format(&dt),
   "17 Friday"
);

In FixedCalendarDateTimeFormatter:

use icu::calendar::Date;
use icu::calendar::Gregorian;
use icu::datetime::FixedCalendarDateTimeFormatter;
use icu::datetime::fieldset::DE;
use icu::locale::locale;
use writeable::assert_try_writeable_eq;

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

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

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

Fields (Non-exhaustive)§

This struct is marked as 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: NeoSkeletonLength

The desired length of the formatted string.

See: NeoSkeletonLength

§alignment: Option<Alignment>

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

See: Alignment
