impl Clone for HijriTabular

fn clone(&self) -> HijriTabular

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HijriTabular

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

impl Default for HijriTabular

fn default() -> HijriTabular

Returns the “default value” for a type.

impl From<HijriTabular> for AnyCalendar

fn from(value: HijriTabular) -> AnyCalendar

Converts to this type from the input type.

impl Hash for HijriTabular

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,

impl IntoAnyCalendar for HijriTabular

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<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 HijriTabular

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

fn eq(&self, other: &HijriTabular) -> 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 HijriTabular

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