Struct icu_datetime::fieldsets::MDET

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

“Fri, May 17, 3:47:50 PM” ⇒ month, day, and weekday with time

Examples

In DateTimeFormatter:

use icu::calendar::DateTime;
use icu::datetime::DateTimeFormatter;
use icu::datetime::fieldsets::MDET;
use icu::locale::locale;
use writeable::assert_writeable_eq;

let fmt = DateTimeFormatter::try_new(
    locale!("en").into(),
   MDET::medium(),
)
.unwrap();
let dt = DateTime::try_new_iso(2024, 5, 17, 15, 47, 50).unwrap();

assert_writeable_eq!(
    fmt.format_any_calendar(&dt),
   "Fri, May 17, 3:47:50 PM"
);

In FixedCalendarDateTimeFormatter:

use icu::calendar::DateTime;
use icu::calendar::Gregorian;
use icu::datetime::FixedCalendarDateTimeFormatter;
use icu::datetime::fieldsets::MDET;
use icu::locale::locale;
use writeable::assert_writeable_eq;

let fmt = FixedCalendarDateTimeFormatter::try_new(
    locale!("en").into(),
   MDET::medium(),
)
.unwrap();
let dt = DateTime::try_new_gregorian(2024, 5, 17, 15, 47, 50).unwrap();

assert_writeable_eq!(
    fmt.format(&dt),
   "Fri, May 17, 3:47:50 PM"
);

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: 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

time_precision: Option<TimePrecision>

How precisely to display the time of day

See: TimePrecision
