Struct YearMonth

pub struct YearMonth {
    pub year: Year,
    pub month: Month,
}

A month-year pair.

Fields

year: Year

month: Month

Implementations

impl YearMonth

pub fn day_count(&self) -> i8

Returns the number of days in this month. This can be definitely known, as the paired year determines whether it’s a leap year, so there’s no chance of being caught out by February.

Examples

use datetime::Year;
use datetime::Month::February;

assert_eq!(Year(2000).month(February).day_count(), 29);
assert_eq!(Year(1900).month(February).day_count(), 28);

pub fn days<S: DaySpan>(&self, span: S) -> MonthDays

Returns an iterator over a continuous span of days in this month, returning LocalDate values.

Examples

use datetime::Year;
use datetime::Month::September;

let ym = Year(1999).month(September);
assert_eq!(ym.days(..).count(), 30);
assert_eq!(ym.days(10 ..).count(), 21);
assert_eq!(ym.days(10 .. 20).count(), 10);
assert_eq!(ym.days(.. 20).count(), 19);

pub fn day(&self, day: i8) -> Result<LocalDate, Error>

Returns a LocalDate based on the day of this month.

This is just a short-cut for the LocalDate::ymd constructor.

Trait Implementations

impl Clone for YearMonth

fn clone(&self) -> YearMonth

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for YearMonth

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for YearMonth

fn eq(&self, other: &YearMonth) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
