Struct DateTime 

pub struct DateTime {
    pub days: i64,
    pub seconds: u32,
}

A calendar date with an optional time of day, without a time zone.

Fields

days: i64

Days since 1970-01-01 (negative before).

seconds: u32

Seconds since midnight.

Implementations

impl DateTime

pub fn from_ymd(year: i32, month: u32, day: u32) -> Option<DateTime>

The date year-month-day at midnight, or None if it does not exist.

pub fn ymd(self) -> (i32, u32, u32)

Year, month (1–12) and day (1–31).

pub fn hms(self) -> (u32, u32, u32)

Hours, minutes and seconds.

pub fn weekday(self) -> u32

Day of the week, 0 = Sunday.

pub fn parse(s: &str) -> Option<DateTime>

Parses ISO 8601 dates: 2026-11-01, 2026-11-01T14:30, 2026-11-01 14:30:05 (a trailing zone such as Z or -03:00 is accepted and ignored).

pub fn now() -> DateTime

The current local date and time in the browser; the current UTC date and time elsewhere (the standard library has no time zones).

pub fn add_days(self, n: i64) -> DateTime

The date n days later (earlier for negative n).

pub fn add_months(self, n: i64) -> DateTime

The same day n months later, clamped to the month’s last day.
