Struct icu_calendar::chinese_based::ChineseBasedYearInfo

pub(crate) struct ChineseBasedYearInfo {
    days_in_prev_year: u16,
    packed_data: PackedChineseBasedYearInfo,
}

A data struct used to load and use information for a set of ChineseBasedDates

Fields

days_in_prev_year: u16

packed_data: PackedChineseBasedYearInfo

Contains:

• length of each month in the year
• whether or not there is a leap month, and which month it is
• the date of Chinese New Year in the related ISO year

Implementations

impl ChineseBasedYearInfo

pub(crate) fn new( days_in_prev_year: u16, packed_data: PackedChineseBasedYearInfo, ) -> Self

pub(crate) fn new_year<CB: ChineseBased>(self, extended_year: i32) -> RataDie

Get the new year R.D. given the extended year that this yearinfo is for

fn next_new_year<CB: ChineseBased>(self, extended_year: i32) -> RataDie

Get the next new year R.D. given the extended year that this yearinfo is for (i.e, this year, not next year)

pub(crate) fn leap_month(self) -> Option<NonZeroU8>

Get which month is the leap month. This produces the month number that is the leap month (not the ordinal month). In other words, for a year with an M05L, this will return Some(5). Note that the regular month precedes the leap month.

fn last_day_of_previous_month(self, month: u8) -> u16

The last day of year in the previous month. month is 1-indexed, and the returned value is also a 1-indexed day of year

Will be zero for the first month as the last day of the previous month is not in this year

fn days_in_year(self) -> u16

fn days_in_prev_year(self) -> u16

fn last_day_of_month(self, month: u8) -> u16

The last day of year in the current month. month is 1-indexed, and the returned value is also a 1-indexed day of year

Will be zero for the first month as the last day of the previous month is not in this year

fn days_in_month(self, month: u8) -> u8

Trait Implementations

impl Clone for ChineseBasedYearInfo

fn clone(&self) -> ChineseBasedYearInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ChineseBasedYearInfo

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

Formats the value using the given formatter.

impl Ord for ChineseBasedYearInfo

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

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

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

impl<'b, CB: ChineseBased> PrecomputedDataSource<ChineseBasedYearInfo> for ChineseBasedPrecomputedData<'b, CB>

fn load_or_compute_info(&self, extended_year: i32) -> ChineseBasedYearInfo

Given a calendar year, load (or compute) the YearInfo for it
