Struct chrono::naive::IsoWeek [−][src]
ISO 8601 week.
This type, combined with Weekday
,
constitues the ISO 8601 week date.
One can retrieve this type from the existing Datelike
types
via the Datelike::iso_week
method.
Implementations
impl IsoWeek
[src]
pub fn year(&self) -> i32
[src]
Returns the year number for this ISO week.
Example
use chrono::{NaiveDate, Datelike, Weekday}; let d = NaiveDate::from_isoywd(2015, 1, Weekday::Mon); assert_eq!(d.iso_week().year(), 2015);
This year number might not match the calendar year number. Continuing the example…
assert_eq!(d.year(), 2014); assert_eq!(d, NaiveDate::from_ymd(2014, 12, 29));
pub fn week(&self) -> u32
[src]
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::{NaiveDate, Datelike, Weekday}; let d = NaiveDate::from_isoywd(2015, 15, Weekday::Mon); assert_eq!(d.iso_week().week(), 15);
pub fn week0(&self) -> u32
[src]
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::{NaiveDate, Datelike, Weekday}; let d = NaiveDate::from_isoywd(2015, 15, Weekday::Mon); assert_eq!(d.iso_week().week0(), 14);

impl Debug for IsoWeek
[src]
The Debug
output of the ISO week w
is the same as
d.format("%G-W%V")
where d
is any NaiveDate
value in that week.
Example
use chrono::{NaiveDate, Datelike}; assert_eq!(format!("{:?}", NaiveDate::from_ymd(2015, 9, 5).iso_week()), "2015-W36"); assert_eq!(format!("{:?}", NaiveDate::from_ymd( 0, 1, 3).iso_week()), "0000-W01"); assert_eq!(format!("{:?}", NaiveDate::from_ymd(9999, 12, 31).iso_week()), "9999-W52");
ISO 8601 requires an explicit sign for years before 1 BCE or after 9999 CE.
assert_eq!(format!("{:?}", NaiveDate::from_ymd( 0, 1, 2).iso_week()), "-0001-W52"); assert_eq!(format!("{:?}", NaiveDate::from_ymd(10000, 12, 31).iso_week()), "+10000-W52");
