Implementations

impl Date

pub fn new( year: i32, day_of_year: u16, ) -> Result<Date, GreaterThanEqualToValueError<u16>>

Constructs a new date given the provided gregorian year and day of year. Returns Err(GreaterThanEqualToValueError) if day_of_year is outside the valid range.

pub fn try_from_values( year: i32, month: u8, day: u8, ) -> Result<Date, GreaterThanEqualToValueError<u8>>

Constructs a new date given the provided values. If month or day is out of range, will return Err(OutsideRangeError).

Note: The ‘day’ parameter here is in the range of 1..=31 as would be shown on a calendar

pub fn try_from( year: i32, month: Month, day: u8, ) -> Result<Date, GreaterThanEqualToValueError<u8>>

Constructs a new date given the provided values, if day is out of range, will return Err(OutsideRangeError)

Note: The ‘day’ parameter here is in the range of 1..=31 as would be shown on a calendar

pub fn year(&self) -> i32

Returns the gregorian year this date represents

pub fn day_of_year_offset(&self) -> u16

Returns the day offset into the year. January 1 is ‘0’, January 31 is ‘30’, February 1 is ‘31’, and so on.

pub fn day_of_year(&self) -> u16

Returns the calendar day of the year. January 1 is ‘1’, January 31 is ‘31’, February 1 is ‘32’, and so on.

pub fn month_of_year(&self) -> Month

Returns the Month this date is contained within

pub fn day_of_month(&self) -> u8

Returns the day index into the current month in the range [0,31)

pub fn add_days(&self, days: u32) -> Date

Adds the specified number of days to this date.

pub fn sub_days(&self, days: u16) -> Date

Subtracts the given number of days from this date

pub fn add_years(&self, years: u16) -> Date

Adds the specified number of years to this date.

pub fn sub_years(&self, years: u16) -> Date

Subtracts the specified number of years from this date.

pub fn as_unix_timestamp(&self) -> UnixTimestamp

Returns the UnixTimestamp of this Date

pub fn as_julian_day(&self) -> JulianDate

Returns the JulianDate of this date

pub fn format<F: Format<Self>>(&self, format: &F) -> String

Formats this date using the specified formatter

pub fn parse_from<F: FormatParser<Self>>( format: &F, string: &str, ) -> Result<Self, FormatError>

Attempts to parse a date from the string using the specified formatter

pub fn day_of_week(&self) -> DayOfWeek

Returns the day-of-the-week name of this date, using ISO8601 convention that the week starts on Monday.

pub fn week_number(&self) -> (i32, u8)

Returns a pair (year number, week of year)
