Struct YearMonth 

pub struct YearMonth { /* private fields */ }

Year + month pair, with no day component. Used by Calendar to track the visible month independently of the current selection.

Stored as a Date anchored on the first of the month; the widget never reads the day field.

Implementations

impl YearMonth

pub fn new(year: i16, month: i8) -> Self

Construct a YearMonth. Year clamps to jiff’s -9999..=9999 range; month clamps to 1..=12.

pub fn year(self) -> i16

Year as i16. Range matches jiff: -9999..=9999.

pub fn month(self) -> i8

Month as i8 in 1..=12.

pub fn first_day(self) -> Date

First day of this month as a Date.

pub fn last_day(self) -> Date

Last day of this month as a Date.

pub fn from_date(d: Date) -> Self

YearMonth containing the given date.

pub fn next_month(self) -> Self

The next calendar month (wraps year on December → January).

pub fn prev_month(self) -> Self

The previous calendar month (wraps year on January → December).

pub fn offset_months(self, n: i32) -> Self

n months later (negative for earlier).
