Struct Date 

pub struct Date { /* private fields */ }

A calendar date (year, month, day), always valid.

use ravenrs_widgets::Date;

let d = Date::new(2026, 1, 31).unwrap();
assert_eq!(d.add_months(1).to_string(), "2026-02-28");
assert_eq!(d.add_days(1).short(), "Feb 1, 2026");
assert!(Date::new(2026, 2, 30).is_none());

Implementations

impl Date

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

Returns None for impossible dates (e.g. February 30).

pub fn year(self) -> i32

The year, e.g. 2026.

pub fn month(self) -> u8

The month, 1 = January … 12 = December.

pub fn day(self) -> u8

The day of the month, starting at 1.

pub fn weekday(self) -> u8

Day of the week, 0 = Sunday … 6 = Saturday.

pub fn first_of_month(self) -> Self

The first day of this date’s month.

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

Moves by whole months, clamping the day (Jan 31 + 1 month = Feb 28/29).

pub fn add_days(self, days: i32) -> Self

Moves by days (negative goes back).

pub fn to_days(self) -> i64

Days since 1970-01-01.

pub fn from_days(days: i64) -> Self

The date days days after 1970-01-01 (inverse of Date::to_days).

pub fn month_title(self) -> String

“October 2026”.

pub fn short(self) -> String

“Oct 31, 2026”.
