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.

impl Eq 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.

[+] Show hidden undocumented items

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

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

Converts an u64 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

pub fn from_isize(n: isize) -> Option<Self>[−]

Converts an isize to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

pub fn from_i8(n: i8) -> Option<Self>[−]

Converts an i8 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

pub fn from_i16(n: i16) -> Option<Self>[−]

Converts an i16 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

pub fn from_i32(n: i32) -> Option<Self>[−]

Converts an i32 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

pub fn from_i128(n: i128) -> Option<Self>[−]

Converts an i128 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

pub fn from_usize(n: usize) -> Option<Self>[−]

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());
