Struct gregorian::Year

pub struct Year { /* private fields */ }

A calendar year.

All dates in the library use the proleptic Gregorian calendar with a year 0.

Implementations

impl Year

pub const fn new(year: i16) -> Self

Create a new year from a number.

pub const fn to_number(self) -> i16

Get the year number.

pub const fn has_leap_day(self) -> bool

Check if the year has a leap day.

In the proleptic Gregorian calendar with a year 0, the year 0 has a leap day.

pub const fn total_days(self) -> u16

Get the total number of days in the year.

For leap years, this is 366. For other years, this is 365.

pub const fn next(self) -> Self

Get the next year.

pub const fn prev(self) -> Self

Get the previous year.

pub const fn with_month(self, month: Month) -> YearMonth

Combine the year with a month to create a YearMonth.

pub const fn with_day_of_year(
    self,
    day_of_year: u16
) -> Result<Date, InvalidDayOfYear>

Combine the year with a day-of-year to create a Date.

Day-of-year numbers start a 1 for January 1.

pub const fn first_month(self) -> YearMonth

Get the first month of the year as YearMonth.

pub const fn last_month(self) -> YearMonth

Get the last month of the year as YearMonth.

pub const fn months(self) -> [YearMonth; 12]

Get all months of the year as YearMonth array.

pub const fn first_day(self) -> Date

Get the first day of the year as Date.

pub const fn last_day(self) -> Date

Get the last day of the year as Date.
