Enum rrule::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.

Trait Implementations

impl Clone for Weekday

pub fn clone(&self) -> Weekday

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Weekday

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Display for Weekday

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

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.

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

Converts an i64 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

pub 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.

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.

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.

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.

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.

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.

fn from_usize(n: usize) -> Option<Self>

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

fn from_u8(n: u8) -> Option<Self>

Converts an u8 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_u16(n: u16) -> Option<Self>

Converts an u16 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_u32(n: u32) -> Option<Self>

Converts an u32 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_u128(n: u128) -> Option<Self>

Converts an u128 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_f32(n: f32) -> Option<Self>

Converts a f32 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_f64(n: f64) -> Option<Self>

Converts a f64 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

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.

pub fn from_str(s: &str) -> Result<Weekday, <Weekday as FromStr>::Err>

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

impl Hash for Weekday

pub fn hash<__H>(&self, state: &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 PartialEq<Weekday> for Weekday

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

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

#[must_use]

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

This method tests for !=.
