Struct icu_calendar::provider::chinese_based::ChineseBasedCacheV1

pub struct ChineseBasedCacheV1<'data> {
    pub first_extended_year: i32,
    pub data: ZeroVec<'data, PackedChineseBasedYearInfo>,
}

Cached/precompiled data for a certain range of years for a chinese-based calendar. Avoids the need to perform lunar calendar arithmetic for most calendrical operations.

Fields

first_extended_year: i32

The extended year corresponding to the first data entry for this year

data: ZeroVec<'data, PackedChineseBasedYearInfo>

A list of precomputed data for each year beginning with first_extended_year

Implementations

impl<'data> ChineseBasedCacheV1<'data>

pub(crate) fn get_for_extended_year( &self, extended_year: i32, ) -> Option<ChineseBasedYearInfo>

Get the cached data for a given extended year

pub(crate) fn get_for_iso<CB: ChineseBased>( &self, iso: ArithmeticDate<Iso>, ) -> Option<(ChineseBasedYearInfo, i32)>

Get the cached data for the Chinese Year corresponding to a given day.

Also returns the corresponding extended year.

Trait Implementations

impl<'data> Clone for ChineseBasedCacheV1<'data>

fn clone(&self) -> ChineseBasedCacheV1<'data>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'data> Debug for ChineseBasedCacheV1<'data>

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

Formats the value using the given formatter.

impl<'data> Default for ChineseBasedCacheV1<'data>

fn default() -> ChineseBasedCacheV1<'data>

Returns the “default value” for a type.

impl<'data> PartialEq for ChineseBasedCacheV1<'data>

fn eq(&self, other: &ChineseBasedCacheV1<'data>) -> 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<'a> Yokeable<'a> for ChineseBasedCacheV1<'static>

type Output = ChineseBasedCacheV1<'a>

This type MUST be Self with the 'static replaced with 'a, i.e. Self<'a>

fn transform(&'a self) -> &'a Self::Output

This method must cast self between &'a Self<'static> and &'a Self<'a>.

fn transform_owned(self) -> Self::Output

This method must cast self between Self<'static> and Self<'a>.

unsafe fn make(this: Self::Output) -> Self

This method can be used to cast away Self<'a>’s lifetime.

fn transform_mut<F>(&'a mut self, f: F)

where F: 'static + for<'b> FnOnce(&'b mut Self::Output),

This method must cast self between &'a mut Self<'static> and &'a mut Self<'a>, and pass it to f.

impl<'zf, 'zf_inner> ZeroFrom<'zf, ChineseBasedCacheV1<'zf_inner>> for ChineseBasedCacheV1<'zf>

fn zero_from(this: &'zf ChineseBasedCacheV1<'zf_inner>) -> Self

Clone the other C into a struct that may retain references into C.
