Struct icu::datetime::fieldset::MDE

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

“Fri, May 17” ⇒ month, day, and weekday

Examples

In DateTimeFormatter:

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

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

In FixedCalendarDateTimeFormatter:

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

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

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

See CLDR-18040 for progress on improving this format.

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: 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
