impl IsoWeek

const fn year(self: &Self) -> i32

Returns the year number for this ISO week.

Example

use chrono::{Datelike, NaiveDate, Weekday};

let d = NaiveDate::from_isoywd_opt(2015, 1, Weekday::Mon).unwrap();
assert_eq!(d.iso_week().year(), 2015);

This year number might not match the calendar year number. Continuing the example...

# use chrono::{NaiveDate, Datelike, Weekday};
# let d = NaiveDate::from_isoywd_opt(2015, 1, Weekday::Mon).unwrap();
assert_eq!(d.year(), 2014);
assert_eq!(d, NaiveDate::from_ymd_opt(2014, 12, 29).unwrap());

const fn week(self: &Self) -> u32

Returns the ISO week number starting from 1.

The return value ranges from 1 to 53. (The last week of year differs by years.)

Example

use chrono::{Datelike, NaiveDate, Weekday};

let d = NaiveDate::from_isoywd_opt(2015, 15, Weekday::Mon).unwrap();
assert_eq!(d.iso_week().week(), 15);

const fn week0(self: &Self) -> u32

Returns the ISO week number starting from 0.

The return value ranges from 0 to 52. (The last week of year differs by years.)

Example

use chrono::{Datelike, NaiveDate, Weekday};

let d = NaiveDate::from_isoywd_opt(2015, 15, Weekday::Mon).unwrap();
assert_eq!(d.iso_week().week0(), 14);
