Transition rule day

Variants

Julian1WithoutLeap(u16)

Julian day in [1, 365], without taking occasional Feb 29 into account, which is not referenceable

Julian0WithLeap(u16)

Zero-based Julian day in [0, 365], taking occasional Feb 29 into account

MonthWeekday

Day represented by a month, a month week and a week day

Fields

month: u8

Month in [1, 12]

week: u8

Week of the month in [1, 5], with 5 representing the last week of the month

week_day: u8

Day of the week in [0, 6] from Sunday

Implementations

impl RuleDay

fn parse( cursor: &mut Cursor<'_>, use_string_extensions: bool, ) -> Result<(Self, i32), Error>

Parse transition rule

fn julian_1(julian_day_1: u16) -> Result<Self, Error>

Construct a transition rule day represented by a Julian day in [1, 365], without taking occasional Feb 29 into account, which is not referenceable

const fn julian_0(julian_day_0: u16) -> Result<Self, Error>

Construct a transition rule day represented by a zero-based Julian day in [0, 365], taking occasional Feb 29 into account

fn month_weekday(month: u8, week: u8, week_day: u8) -> Result<Self, Error>

Construct a transition rule day represented by a month, a month week and a week day

fn transition_date(&self, year: i32) -> (usize, i64)

Get the transition date for the provided year

Outputs

• month: Month in [1, 12]
• month_day: Day of the month in [1, 31]

fn unix_time(&self, year: i32, day_time_in_utc: i64) -> i64

Returns the UTC Unix time in seconds associated to the transition date for the provided year

Trait Implementations

impl Clone for RuleDay

fn clone(&self) -> RuleDay

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RuleDay

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

Formats the value using the given formatter.

impl PartialEq for RuleDay

fn eq(&self, other: &RuleDay) -> 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.
