Struct icu_calendar::iso::Iso

pub struct Iso;

The ISO Calendar

The ISO Calendar is a standardized solar calendar with twelve months. It is identical to the Gregorian calendar, except it uses negative years for years before 1 CE, and may have differing formatting data for a given locale.

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

Era codes

This calendar supports one era, "default"

Implementations

impl Iso

pub fn new() -> Self

Trait Implementations

impl Calendar for Iso

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

The calendar-specific year represented by date

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

type DateInner = IsoDateInner

The internal type used to represent dates

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

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) -> u32

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 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 Clone for Iso

fn clone(&self) -> Iso

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Iso

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

Formats the value using the given formatter.

impl Default for Iso

fn default() -> Iso

Returns the “default value” for a type.

impl Hash for Iso

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 Iso

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 PartialEq<Iso> for Iso

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