Struct Date 

pub struct Date { /* private fields */ }

A calendar date. Construct with Date::new, which validates.

Implementations

impl Date

pub fn new(year: i32, month: u32, day: u32) -> Option<Date>

A validated date, or None for impossible ones (Feb 30, month 13, …).

pub fn today() -> Date

Today in UTC (std has no timezone database; a calendar highlight is the intended use, not civil timekeeping).

pub fn year(self) -> i32

pub fn month(self) -> u32

pub fn day(self) -> u32

pub fn to_days(self) -> i64

Days since 1970-01-01.

pub fn from_days(days: i64) -> Date

The date days after 1970-01-01.

pub fn weekday(self) -> Weekday

pub fn add_days(self, days: i64) -> Date

pub fn add_months(self, months: i32) -> Date

Shift by whole months, clamping the day to the target month’s length (Jan 31 + 1 month = Feb 28/29).

pub fn month_name(self) -> &'static str

pub fn format(self, pattern: &str) -> String

Render through a token pattern. Tokens: YYYY, MM, M, DD, D, MMM (Jan), MMMM (January). Anything else passes through.

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

Parse "YYYY-MM-DD" (also tolerates single-digit month/day).
