Struct icu::datetime::fieldset::Zs

#[non_exhaustive]
pub struct Zs { pub length: NeoSkeletonLength, }
Expand description

“CDT” ⇒ time zone in specific non-location format (only short)

This field set can be used only in combination with others.

§Examples

In DateTimeFormatter:

 use icu::calendar::{Date, Time};
 use icu::timezone::{TimeZoneBcp47Id, TimeZoneInfo, UtcOffset, ZoneVariant};
 use icu::datetime::DateTimeFormatter;
use icu::datetime::fieldset::Zs;
 use icu::locale::locale;
 use tinystr::tinystr;
 use writeable::assert_try_writeable_eq;

let fmt = DateTimeFormatter::<Zs>::try_new(
     &locale!("en").into(),
    Zs::short(),
 )
 .unwrap();

 // Time zone info for America/Chicago in the summer
 let zone = TimeZoneBcp47Id(tinystr!(8, "uschi"))
     .with_offset("-05".parse().ok())
     .at_time((Date::try_new_iso(2022, 8, 29).unwrap(), Time::midnight()))
     .with_zone_variant(ZoneVariant::Daylight);

 assert_try_writeable_eq!(
     fmt.convert_and_format(&zone),
    "CDT"
 );

In FixedCalendarDateTimeFormatter:

 use icu::calendar::{Date, Time};
 use icu::timezone::{TimeZoneBcp47Id, TimeZoneInfo, UtcOffset, ZoneVariant};
 use icu::calendar::Gregorian;
 use icu::datetime::FixedCalendarDateTimeFormatter;
use icu::datetime::fieldset::Zs;
 use icu::locale::locale;
 use tinystr::tinystr;
 use writeable::assert_try_writeable_eq;

let fmt = FixedCalendarDateTimeFormatter::<Gregorian, Zs>::try_new(
     &locale!("en").into(),
    Zs::short(),
 )
 .unwrap();

 // Time zone info for America/Chicago in the summer
 let zone = TimeZoneBcp47Id(tinystr!(8, "uschi"))
     .with_offset("-05".parse().ok())
     .at_time((Date::try_new_iso(2022, 8, 29).unwrap(), Time::midnight()))
     .with_zone_variant(ZoneVariant::Daylight);

 assert_try_writeable_eq!(
     fmt.format(&zone),
    "CDT"
 );

This style requires a ZoneVariant, so only a full time zone info can be formatted with this style. For example, [TimeZoneInfo<AtTime>] cannot be formatted.

use icu::calendar::{DateTime, Iso};
use icu::datetime::FixedCalendarDateTimeFormatter;
use icu::datetime::fieldset::{Combo, T, Zs};
use icu::timezone::{TimeZoneBcp47Id, UtcOffset, ZoneVariant};
use tinystr::tinystr;
use icu::locale::locale;
use writeable::assert_try_writeable_eq;

let datetime = DateTime::try_new_gregorian(2024, 10, 18, 0, 0, 0).unwrap();
let time_zone_basic = TimeZoneBcp47Id(tinystr!(8, "uschi")).with_offset("-06".parse().ok());
let time_zone_at_time = time_zone_basic.at_time((datetime.date.to_iso(), datetime.time));

let formatter = FixedCalendarDateTimeFormatter::try_new(
    &locale!("en-US").into(),
    Combo::<T, Zs>::medium(),
)
.unwrap();

// error[E0271]: type mismatch resolving `<AtTime as TimeZoneModel>::ZoneVariant == ZoneVariant`
// note: required by a bound in `FixedCalendarDateTimeFormatter::<C, FSet>::format`
formatter.format(&time_zone_at_time);

Fields (Non-exhaustive)§

This struct is marked as 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.
