Struct Iso

pub struct Iso;

The ISO-8601 Calendar

The ISO-8601 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 to represent dates in this calendar.

Era codes

This calendar uses a single era: default

Implementations

impl Iso

pub fn new() -> Iso

Trait Implementations

impl Calendar for Iso

fn date_from_codes( &self, era: Option<&str>, year: i32, month_code: MonthCode, day: u8, ) -> Result<<Iso as Calendar>::DateInner, DateError>

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) -> Weekday

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 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,

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.
