Struct Ethiopian

pub struct Ethiopian(/* private fields */);

The Ethiopian Calendar

The Ethiopian 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 to represent dates in this calendar.

It can be constructed in two modes: using the Amete Alem era scheme, or the Amete Mihret era scheme (the default), see EthiopianEraStyle for more info.

Era codes

This calendar always uses the aa era, where 1 Amete Alem is 5493 BCE. Dates before this era use negative years. Dates before that use negative year numbers. In the Amete Mihret scheme it uses the additional am era, 1 Amete Mihret is 9 CE.

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 calendar_algorithm(&self) -> Option<CalendarAlgorithm>

Returns the CalendarAlgorithm that is required to match when parsing into this calendar.

impl Clone for Ethiopian

fn clone(&self) -> Ethiopian

Returns a copy of the value.

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

impl Debug for Ethiopian

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

Formats the value using the given formatter.

impl Default for Ethiopian

fn default() -> Ethiopian

Returns the “default value” for a type.

impl From<Ethiopian> for AnyCalendar

fn from(value: Ethiopian) -> AnyCalendar

Converts to this type from the input type.

impl Hash for Ethiopian

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn kind(&self) -> AnyCalendarKind

The AnyCalendarKind enum variant associated with this calendar

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

Convert an AnyCalendar reference into a Self reference.

fn date_to_any(&self, d: &Self::DateInner) -> AnyDateInner

impl Ord for Ethiopian

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

impl PartialEq for Ethiopian

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

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

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
