impl Julian

pub fn new() -> Julian

Construct a new Julian Calendar

Trait Implementations

impl Calendar for Julian

fn year(&self, date: &<Julian as Calendar>::DateInner) -> FormattableYear

The calendar-specific year represented by date Julian has the same era scheme as Gregorian

fn month(&self, date: &<Julian as Calendar>::DateInner) -> FormattableMonth

The calendar-specific month represented by date

fn day_of_month(&self, date: &<Julian as Calendar>::DateInner) -> DayOfMonth

The calendar-specific day-of-month represented by date

type DateInner = JulianDateInner

The internal type used to represent dates

fn date_from_codes( &self, era: Era, year: i32, month_code: MonthCode, day: u8 ) -> Result<<Julian as Calendar>::DateInner, CalendarError>

Construct a date from era/month codes and fields

fn date_from_iso(&self, iso: Date<Iso>) -> JulianDateInner

Construct the date from an ISO date

fn date_to_iso(&self, date: &<Julian as Calendar>::DateInner) -> Date<Iso>

Obtain an ISO date from this date

fn months_in_year(&self, date: &<Julian as Calendar>::DateInner) -> u8

Count the number of months in a given year, specified by providing a date from that year

fn days_in_year(&self, date: &<Julian as Calendar>::DateInner) -> u32

Count the number of days in a given year, specified by providing a date from that year

fn days_in_month(&self, date: &<Julian as Calendar>::DateInner) -> u8

Count the number of days in a given month, specified by providing a date from that year/month

fn day_of_week(&self, date: &<Julian as Calendar>::DateInner) -> IsoWeekday

Calculate the day of the week and return it

fn day_of_year_info( &self, date: &<Julian as Calendar>::DateInner ) -> DayOfYearInfo

Information of the day of the year

fn debug_name(&self) -> &'static str

Obtain a name for the calendar for debug printing

fn any_calendar_kind(&self) -> Option<AnyCalendarKind>

The AnyCalendarKind corresponding to this calendar, if one exists. Implementors outside of icu_calendar should return None

impl Clone for Julian

fn clone(&self) -> Julian

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Julian

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for Julian

fn default() -> Julian

Returns the “default value” for a type.

impl Hash for Julian

fn hash<__H>(&self, state: &mut __H)where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<Julian> for Julian

fn eq(&self, other: &Julian) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
