“3:47:50 PM” ⇒ locale-dependent time fields

Examples

In NeoFormatter:

use icu::calendar::DateTime;
use icu::datetime::neo::NeoFormatter;
use icu::datetime::neo_marker::NeoAutoTimeMarker;
use icu::datetime::neo_skeleton::NeoSkeletonLength;
use icu::locale::locale;
use writeable::assert_try_writeable_eq;

let fmt = NeoFormatter::<NeoAutoTimeMarker>::try_new(
    &locale!("en").into(),
   NeoAutoTimeMarker::with_length(NeoSkeletonLength::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 TypedNeoFormatter:

use icu::calendar::Time;
use icu::calendar::Gregorian;
use icu::datetime::neo::TypedNeoFormatter;
use icu::datetime::neo_marker::NeoAutoTimeMarker;
use icu::datetime::neo_skeleton::NeoSkeletonLength;
use icu::locale::locale;
use writeable::assert_try_writeable_eq;

let fmt = TypedNeoFormatter::<Gregorian, NeoAutoTimeMarker>::try_new(
    &locale!("en").into(),
   NeoAutoTimeMarker::with_length(NeoSkeletonLength::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

fractional_second_digits: Option<FractionalSecondDigits>

How many fractional seconds to display.

See: FractionalSecondDigits
