pub struct ExemplarCity;
Expand description
“Chicago” ⇒ time zone in exemplar city format
§Examples
use icu::datetime::input::Date;
use icu::datetime::input::{Time, TimeZone,TimeZoneInfo, UtcOffset};
use icu::datetime::NoCalendarFormatter;
use icu::time::zone::TimeZoneVariant;
use icu::datetime::fieldsets::zone::ExemplarCity;
use icu::locale::locale;
use tinystr::tinystr;
use writeable::assert_writeable_eq;
let fmt = NoCalendarFormatter::try_new(
locale!("en").into(),
ExemplarCity
)
.unwrap();
// Time zone info for America/Chicago in the summer
let zone = TimeZone(tinystr!(8, "uschi"))
.with_offset("-05".parse().ok())
.at_time((Date::try_new_iso(2022, 8, 29).unwrap(), Time::midnight()))
.with_zone_variant(TimeZoneVariant::Daylight);
assert_writeable_eq!(
fmt.format(&zone),
"Chicago"
);
A time zone ID is required to format with this style.
For example, a raw UtcOffset
cannot be used here.
