Struct icu_calendar::coptic::Coptic

pub struct Coptic;

The Coptic Calendar

The Coptic calendar is a solar calendar used by the Coptic Orthodox Church, with twelve normal months and a thirteenth small epagomenal month.

This type can be used with Date or DateTime to represent dates in this calendar.

Era codes

This calendar supports two era codes: "bd", and "ad", corresponding to the Before Diocletian and After Diocletian/Anno Martyrum eras. 1 A.M. is equivalent to 284 C.E.

Month codes

This calendar supports 13 solar month codes ("M01" - "M13"), with "M13" being used for the short epagomenal month at the end of the year.

Trait Implementations

impl Calendar for Coptic

type DateInner = CopticDateInner

The internal type used to represent dates

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

Construct a date from era/month codes and fields

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

Construct the date from an ISO date

fn date_to_iso(&self, date: &Self::DateInner) -> Date<Iso>

Obtain an ISO date from this date

fn months_in_year(&self, date: &Self::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: &Self::DateInner) -> u16

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

fn days_in_month(&self, date: &Self::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: &Self::DateInner) -> IsoWeekday

Calculate the day of the week and return it

fn year(&self, date: &Self::DateInner) -> FormattableYear

The calendar-specific year represented by date

fn is_in_leap_year(&self, date: &Self::DateInner) -> bool

Calculate if a date is in a leap year

fn month(&self, date: &Self::DateInner) -> FormattableMonth

The calendar-specific month represented by date

fn day_of_month(&self, date: &Self::DateInner) -> DayOfMonth

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

fn day_of_year_info(&self, date: &Self::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 CalendarArithmetic for Coptic

type YearInfo = ()

In case we plan to cache per-year data, this stores useful computational information for the current year as a field on ArithmeticDate

fn month_days(year: i32, month: u8, _data: ()) -> u8

fn months_for_every_year(_: i32, _data: ()) -> u8

fn is_leap_year(year: i32, _data: ()) -> bool

fn last_month_day_in_year(year: i32, _data: ()) -> (u8, u8)

fn days_in_provided_year(year: i32, _data: ()) -> u16

Calculate the days in a given year Can be overridden with simpler implementations for solar calendars (typically, 366 in leap, 365 otherwise) Leave this as the default for lunar calendars

impl Clone for Coptic

fn clone(&self) -> Coptic

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Coptic

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

Formats the value using the given formatter.

impl Default for Coptic

fn default() -> Coptic

Returns the “default value” for a type.

impl Hash for Coptic

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

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 IntoAnyCalendar for Coptic

fn to_any(self) -> AnyCalendar

Convert this calendar into an AnyCalendar, moving it

fn to_any_cloned(&self) -> AnyCalendar

Convert this calendar into an AnyCalendar, cloning it

fn date_to_any(&self, d: &Self::DateInner) -> AnyDateInner

Convert a date for this calendar into an AnyDateInner

impl Ord for Coptic

fn cmp(&self, other: &Coptic) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Coptic

fn eq(&self, other: &Coptic) -> 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.

impl PartialOrd for Coptic

fn partial_cmp(&self, other: &Coptic) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
