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.

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<(), Error>

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

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: &<Coptic as Calendar>::DateInner) -> 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.
