Struct SimpleDate 

pub struct SimpleDate {
    pub year: i32,
    pub month: u8,
    pub day: u8,
}

A plain calendar date — year/month/day, no time-of-day or timezone.

Fields

year: i32

month: u8

1-12.

day: u8

1-31.

Implementations

impl SimpleDate

pub fn new(year: i32, month: u8, day: u8) -> Self

pub fn is_leap_year(year: i32) -> bool

pub fn days_in_month(year: i32, month: u8) -> u8

pub fn day_of_week(year: i32, month: u8, day: u8) -> u8

0 = Sunday .. 6 = Saturday, via Zeller’s congruence (Gregorian).

pub fn prev_month(self) -> Self

pub fn next_month(self) -> Self

pub fn prev_year(self) -> Self

pub fn next_year(self) -> Self

pub fn month_ordinal(self) -> i32

Absolute month index (year*12 + month-1) — a monotone integer used to animate month-to-month slides and to compare/step months cheaply.

pub fn from_month_ordinal(ord: i32) -> Self

Inverse of Self::month_ordinal — day defaults to 1.
