Struct icu_calendar::islamic::IslamicCivil

pub struct IslamicCivil;

Civil / Arithmetical Islamic Calendar (Used for administrative purposes)

Trait Implementations

impl Calendar for IslamicCivil

type DateInner = IslamicCivilDateInner

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>) -> Self::DateInner

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 debug_name(&self) -> &'static str

Obtain a name for the calendar for debug printing

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 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 IslamicCivil

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(_year: i32, _data: ()) -> 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

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

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

impl Clone for IslamicCivil

fn clone(&self) -> IslamicCivil

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IslamicCivil

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

Formats the value using the given formatter.

impl Default for IslamicCivil

fn default() -> IslamicCivil

Returns the “default value” for a type.

impl Hash for IslamicCivil

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 IslamicCivil

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 IslamicCivil

fn cmp(&self, other: &IslamicCivil) -> 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 IslamicCivil

fn eq(&self, other: &IslamicCivil) -> 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 IslamicCivil

fn partial_cmp(&self, other: &IslamicCivil) -> 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.
