Enum mysql::chrono::Weekday

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.

Sun

Sunday.

Methods

impl Weekday

fn succ(&self) -> Weekday

The next day in the week.

w:	Mon	Tue	Wed	Thu	Fri	Sat	Sun
w.succ():	Tue	Wed	Thu	Fri	Sat	Sun	Mon

fn pred(&self) -> Weekday

The previous day in the week.

w:	Mon	Tue	Wed	Thu	Fri	Sat	Sun
w.pred():	Sun	Mon	Tue	Wed	Thu	Fri	Sat

fn number_from_monday(&self) -> u32

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

fn number_from_sunday(&self) -> u32

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

fn num_days_from_monday(&self) -> u32

Returns a day-of-week number starting from Monday = 0.

w:	Mon	Tue	Wed	Thu	Fri	Sat	Sun
w.num_days_from_monday():	0	1	2	3	4	5	6

fn num_days_from_sunday(&self) -> u32

Returns a day-of-week number starting from Sunday = 0.

w:	Mon	Tue	Wed	Thu	Fri	Sat	Sun
w.num_days_from_sunday():	1	2	3	4	5	6	0

Trait Implementations

impl FromStr for Weekday

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<Weekday, <Weekday as FromStr>::Err>

Parses a string s to return a value of this type.

impl Eq for Weekday

impl Copy for Weekday

impl FromPrimitive for Weekday

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.

fn from_i64(n: i64) -> Option<Weekday>

fn from_u64(n: u64) -> Option<Weekday>

impl PartialEq<Weekday> for Weekday

fn eq(&self, __arg_0: &Weekday) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Debug for Weekday

fn fmt(&self, __arg_0: &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.

impl Hash for Weekday

fn hash<__H>(&self, __arg_0: &mut __H) where
    __H: Hasher, 

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl Clone for Weekday

fn clone(&self) -> Weekday

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
