Enum chrono::Weekday [−][src]
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.
Implementations
impl Weekday
[src]
pub fn succ(&self) -> Weekday
[src]
The next day in the week.
w : | Mon | Tue | Wed | Thu | Fri | Sat | Sun |
---|---|---|---|---|---|---|---|
w.succ() : | Tue | Wed | Thu | Fri | Sat | Sun | Mon |
pub fn pred(&self) -> Weekday
[src]
The previous day in the week.
w : | Mon | Tue | Wed | Thu | Fri | Sat | Sun |
---|---|---|---|---|---|---|---|
w.pred() : | Sun | Mon | Tue | Wed | Thu | Fri | Sat |
pub fn number_from_monday(&self) -> u32
[src]
Returns a day-of-week number starting from Monday = 1. (ISO 8601 weekday number)
w : | Mon | Tue | Wed | Thu | Fri | Sat | Sun |
---|---|---|---|---|---|---|---|
w.number_from_monday() : | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
pub fn number_from_sunday(&self) -> u32
[src]
Returns a day-of-week number starting from Sunday = 1.
w : | Mon | Tue | Wed | Thu | Fri | Sat | Sun |
---|---|---|---|---|---|---|---|
w.number_from_sunday() : | 2 | 3 | 4 | 5 | 6 | 7 | 1 |

---|---|---|---|---|---|---|---|
w.num_days_from_monday() : | 0 | 1 | 2 | 3 | 4 | 5 | 6 |
pub fn num_days_from_sunday(&self) -> u32
[src]
Returns a day-of-week number starting from Sunday = 0.

[src]
impl Eq for Weekday
[src]
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.

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.
