Struct YearlessDate

pub struct YearlessDate { /* private fields */ }

A yearless date, consisting of a gregorian month and a day within the month, without an associated year.

Examples

use whatwg_datetime::{parse_yearless_date, YearlessDate};

assert_eq!(parse_yearless_date("11-18"), YearlessDate::new_opt(11, 18));

Implementations

impl YearlessDate

pub fn new_opt(month: u32, day: u32) -> Option<Self>

Creates a new YearlessDate from a month and a day.

This asserts that the month is in between 1 through 12, inclusive, and that the day is in the valid range for the month. Specifically:

• February must be between 1 and 29, inclusive
• April, June, September, and November must be between 1 and 30, inclusive
• All other months must be between 1 and 31, inclusive

Examples

use whatwg_datetime::YearlessDate;

assert!(YearlessDate::new_opt(11, 18).is_some());
assert!(YearlessDate::new_opt(2, 29).is_some());
assert!(YearlessDate::new_opt(2, 30).is_none()); // February never has 30 days
assert!(YearlessDate::new_opt(4, 31).is_none()); // April only has 30 days
assert!(YearlessDate::new_opt(13, 1).is_none()); // There are only 12 months
assert!(YearlessDate::new_opt(12, 32).is_none()); // December only has 31 days

pub const fn month(&self) -> u32

A month component. This is a number from 1 to 12, inclusive.

Examples

use whatwg_datetime::YearlessDate;

let yearless_date = YearlessDate::new_opt(11, 18).unwrap();
assert_eq!(yearless_date.month(), 11);

pub const fn day(&self) -> u32

A day component. This is a number from 1 to the max number of days in the month, inclusive.

Examples

use whatwg_datetime::YearlessDate;

let yearless_date = YearlessDate::new_opt(11, 18).unwrap();
assert_eq!(yearless_date.day(), 18);

Trait Implementations

impl Clone for YearlessDate

fn clone(&self) -> YearlessDate

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for YearlessDate

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

Formats the value using the given formatter.

impl PartialEq for YearlessDate

fn eq(&self, other: &YearlessDate) -> 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.
