Type Alias NoCalendarFormatter

pub type NoCalendarFormatter<FSet> = FixedCalendarDateTimeFormatter<(), FSet>;

A formatter optimized for time and time zone formatting, when a calendar is not needed.

Examples

A NoCalendarFormatter can be used to format a time:

use icu::datetime::fieldsets::T;
use icu::datetime::input::Time;
use icu::datetime::NoCalendarFormatter;
use icu::locale::locale;

let formatter =
    NoCalendarFormatter::try_new(locale!("bn").into(), T::long()).unwrap();
assert_eq!(
    formatter.format(&Time::start_of_day()).to_string(),
    "১২:০০:০০ AM"
);

A NoCalendarFormatter cannot be constructed with a fieldset that involves dates:

use icu::datetime::fieldsets::Y;
use icu::datetime::NoCalendarFormatter;
use icu::locale::locale;

assert!(
    NoCalendarFormatter::try_new(locale!("und").into(), Y::medium())
        .is_err()
);

Furthermore, it is a compile error in the format function:

use icu::datetime::NoCalendarFormatter;
use icu::datetime::fieldsets::Y;
use icu::locale::locale;

let date: icu::calendar::Date<icu::calendar::Gregorian> = unimplemented!();
let formatter = NoCalendarFormatter::try_new(locale!("und").into(), Y::medium()).unwrap();

// error[E0271]: type mismatch resolving `<Gregorian as AsCalendar>::Calendar == ()`
formatter.format(&date);
