Struct icu_datetime::fieldset::T

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

“3:47:50 PM” ⇒ time (locale-dependent hour cycle)

Examples

In DateTimeFormatter:

use icu::calendar::DateTime;
use icu::datetime::DateTimeFormatter;
use icu::datetime::fieldset::T;
use icu::locale::locale;
use writeable::assert_try_writeable_eq;

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

assert_try_writeable_eq!(
    fmt.convert_and_format(&dt),
   "3:47:50 PM"
);

In FixedCalendarDateTimeFormatter:

use icu::calendar::Time;
use icu::calendar::Gregorian;
use icu::datetime::FixedCalendarDateTimeFormatter;
use icu::datetime::fieldset::T;
use icu::locale::locale;
use writeable::assert_try_writeable_eq;

let fmt = FixedCalendarDateTimeFormatter::<Gregorian, T>::try_new(
    &locale!("en").into(),
   T::medium(),
)
.unwrap();
let dt = Time::try_new(15, 47, 50, 0).unwrap();

assert_try_writeable_eq!(
    fmt.format(&dt),
   "3:47:50 PM"
);

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

time_precision: Option<TimePrecision>

How precisely to display the time of day

See: TimePrecision

type T = T

Associated types for time formatting.

type Z = NeoNeverMarker

Associated types for time zone formatting.

type GluePatternV1Marker = NeverMarker<GluePatternV1<'static>>

Marker for loading the date/time glue pattern.

impl Debug for T

Formats the value using the given formatter.

impl GetField<()> for T

fn get_field(&self)

Returns the value of this trait’s field T.

impl GetField<CompositeFieldSet> for T

fn get_field(&self) -> CompositeFieldSet

Returns the value of this trait’s field T.

Marker for loading time skeleton patterns.

type HourInput = IsoHour

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

type MinuteInput = IsoMinute

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

type SecondInput = IsoSecond

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

type NanoSecondInput = NanoSecond

Marker for resolving the any-calendar-kind input field.
