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

Monday.

Tuesday.

Wednesday.

Thursday.

Friday.

Saturday.

Sunday.

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());

The associated error which can be returned from parsing.
