Struct icu::calendar::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() -> Iso

Construct a date from era/month codes and fields

fn month(&self, date: &<Iso as Calendar>::DateInner) -> MonthInfo

The calendar-specific month represented by date

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

Obtain an ISO date from this date

fn months_in_year(&self, date: &<Iso 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: &<Iso as Calendar>::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: &<Iso 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: &<Iso as Calendar>::DateInner) -> IsoWeekday

Calculate the day of the week and return it

fn year(&self, date: &<Iso as Calendar>::DateInner) -> YearInfo

Information about the year

fn is_in_leap_year(&self, date: &<Iso as Calendar>::DateInner) -> bool

Calculate if a date is in a leap year

fn day_of_year_info(&self, date: &<Iso 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 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<(), Error>

Formats the value using the given formatter.

impl Default for Iso

fn default() -> Iso

Returns the “default value” for a type.

impl From<Iso> for AnyCalendar

fn from(value: Iso) -> AnyCalendar

Converts to this type from the input type.

impl Hash for Iso

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 IntoAnyCalendar for Iso

fn to_any(self) -> AnyCalendar

Convert this calendar into an AnyCalendar, moving it

fn kind(&self) -> AnyCalendarKind

The AnyCalendarKind enum variant associated with this calendar

fn to_any_cloned(&self) -> AnyCalendar

Convert this calendar into an AnyCalendar, cloning it

fn from_any(any: AnyCalendar) -> Result<Iso, AnyCalendar>

Move an AnyCalendar into a Self, or returning it as an error if the types do not match.

fn from_any_ref(any: &AnyCalendar) -> Option<&Iso>

Convert an AnyCalendar reference into a Self reference.

fn date_to_any(&self, d: &<Iso as Calendar>::DateInner) -> AnyDateInner

Convert a date for this calendar into an AnyDateInner

impl Ord for Iso

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

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for Iso

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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