Struct DayDate 

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

A civil (zoneless) calendar date, proleptic Gregorian. Ordered chronologically; Display and DayDate::parse_iso speak ISO-8601 (YYYY-MM-DD).

Fields

year: i32

month: u8

day: u8

Implementations

impl DayDate

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

A validated date (month 1–12, day within the month, leap-aware); None otherwise.

pub fn today() -> Self

Today’s date derived from the system clock in UTC (Day carries no time-zone database; an app that must roll the date at local midnight should compute it with its own zone source).

pub fn to_epoch_days(self) -> i64

Days since 1970-01-01 (negative before). The numeric interchange form across native boundaries (Event::Custom.num).

pub fn from_epoch_days(days: i64) -> Self

The date days after 1970-01-01 (inverse of DayDate::to_epoch_days).

pub fn parse_iso(s: &str) -> Option<Self>

Parse strict ISO-8601 YYYY-MM-DD (the form Display writes). None on anything else.

pub fn clamped(self, min: Option<DayDate>, max: Option<DayDate>) -> Self

This date limited to the inclusive [min, max] range (either bound optional).
