Enum chrono::Weekday [−][src]
pub enum Weekday {
Mon,
Tue,
Wed,
Thu,
Fri,
Sat,
Sun,
}
Expand description
The day of week.
The order of the days of week depends on the context.
(This is why this type does not implement PartialOrd
or Ord
traits.)
One should prefer *_from_monday
or *_from_sunday
methods to get the correct result.
Variants
Mon
Monday.
Tue
Tuesday.
Wed
Wednesday.
Thu
Thursday.
Fri
Friday.
Sat
Saturday.
Sun
Sunday.

Trait Implementations
Any weekday can be represented as an integer from 0 to 6, which equals to
Weekday::num_days_from_monday
in this implementation.
Do not heavily depend on this though; use explicit methods whenever possible.

Parsing a str
into a Weekday
uses the format %W
.
Example
use chrono::Weekday;
assert_eq!("Sunday".parse::<Weekday>(), Ok(Weekday::Sun));
assert!("any day".parse::<Weekday>().is_err());
The parsing is case-insensitive.
assert_eq!("mON".parse::<Weekday>(), Ok(Weekday::Mon));
Only the shortest form (e.g. sun
) and the longest form (e.g. sunday
) is accepted.
assert!("thurs".parse::<Weekday>().is_err());
