This is a calendar that encompasses all formattable calendars supported by this crate

This allows for the construction of Date objects that have their calendar known at runtime.

This can be constructed by calling .into() on a concrete calendar type if the calendar type is known at compile time. When the type is known at runtime, the AnyCalendar::new() and sibling methods may be used.

Date can also be converted to AnyCalendar-compatible ones via Date::to_any().

There are many ways of constructing an AnyCalendar’d date:

use icu::calendar::{AnyCalendar, AnyCalendarKind, Date, cal::Japanese, types::MonthCode};
use icu::locale::locale;
use tinystr::tinystr;

let locale = locale!("en-u-ca-japanese"); // English with the Japanese calendar

let calendar = AnyCalendar::new(AnyCalendarKind::new(locale.into()));
let calendar = Rc::new(calendar); // Avoid cloning it each time
                                  // If everything is a local reference, you may use icu::calendar::Ref instead.

// construct from era code, year, month code, day, and a calendar
// This is March 28, 15 Heisei
let manual_date = Date::try_new_from_codes(Some("heisei"), 15, MonthCode(tinystr!(4, "M03")), 28, calendar.clone())
                    .expect("Failed to construct Date manually");


// construct another date by converting from ISO
let iso_date = Date::try_new_iso(2020, 9, 1)
    .expect("Failed to construct ISO Date.");
let iso_converted = iso_date.to_calendar(calendar);

// Construct a date in the appropriate typed calendar and convert
let japanese_calendar = Japanese::new();
let japanese_date = Date::try_new_japanese_with_calendar("heisei", 15, 3, 28,
                                                        japanese_calendar).unwrap();
// This is a Date<AnyCalendar>
let any_japanese_date = japanese_date.to_any();
