Enum chrono::Weekday
[−]
[src]
pub enum Weekday { Mon, Tue, Wed, Thu, Fri, Sat, Sun, }
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.

Trait Implementations
impl FromStr for Weekday
[src]
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());
type Err = ParseWeekdayError
The associated error which can be returned from parsing.
fn from_str(s: &str) -> Result<Self, Self::Err>
Parses a string s
to return a value of this type. Read more

impl FromPrimitive for Weekday
[src]
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.
