Examples

In NeoFormatter:

use icu::calendar::Date;
use icu::datetime::neo::NeoFormatter;
use icu::datetime::neo_marker::NeoAutoDateMarker;
use icu::datetime::neo_skeleton::NeoSkeletonLength;
use icu::locale::locale;
use writeable::assert_try_writeable_eq;
let fmt = NeoFormatter::<NeoAutoDateMarker>::try_new(
    &locale!("en").into(),
   NeoAutoDateMarker::with_length(NeoSkeletonLength::Medium),
)
.unwrap();
let dt = Date::try_new_iso(2024, 5, 17).unwrap();

assert_try_writeable_eq!(
    fmt.convert_and_format(&dt),
   "May 17, 2024"
);

In TypedNeoFormatter:

use icu::calendar::Date;
use icu::calendar::Gregorian;
use icu::datetime::neo::TypedNeoFormatter;
use icu::datetime::neo_marker::NeoAutoDateMarker;
use icu::datetime::neo_skeleton::NeoSkeletonLength;
use icu::locale::locale;
use writeable::assert_try_writeable_eq;

let fmt = TypedNeoFormatter::<Gregorian, NeoAutoDateMarker>::try_new(
    &locale!("en").into(),
   NeoAutoDateMarker::with_length(NeoSkeletonLength::Medium),
)
.unwrap();
let dt = Date::try_new_gregorian(2024, 5, 17).unwrap();

assert_try_writeable_eq!(
    fmt.format(&dt),
   "May 17, 2024"
);

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

year_style: Option<YearStyle>

When to display the era field in the formatted string.

See: YearStyle
