Implementations

impl Weekday

pub const fn previous(self) -> Self

Get the previous weekday.

assert_eq!(Weekday::Tuesday.previous(), Weekday::Monday);

pub const fn next(self) -> Self

Get the next weekday.

assert_eq!(Weekday::Monday.next(), Weekday::Tuesday);

pub const fn nth_next(self, n: u8) -> Self

Get n-th next day.

assert_eq!(Weekday::Monday.nth_next(1), Weekday::Tuesday);
assert_eq!(Weekday::Sunday.nth_next(10), Weekday::Wednesday);

pub const fn nth_prev(self, n: u8) -> Self

Get n-th previous day.

assert_eq!(Weekday::Monday.nth_prev(1), Weekday::Sunday);
assert_eq!(Weekday::Sunday.nth_prev(10), Weekday::Thursday);

pub const fn number_from_monday(self) -> u8

Get the one-indexed number of days from Monday.

assert_eq!(Weekday::Monday.number_from_monday(), 1);

pub const fn number_from_sunday(self) -> u8

Get the one-indexed number of days from Sunday.

assert_eq!(Weekday::Monday.number_from_sunday(), 2);

pub const fn number_days_from_monday(self) -> u8

Get the zero-indexed number of days from Monday.

assert_eq!(Weekday::Monday.number_days_from_monday(), 0);

pub const fn number_days_from_sunday(self) -> u8

assert_eq!(Weekday::Monday.number_days_from_sunday(), 1);

Trait Implementations

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.

impl Debug for Weekday

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

Formats the value using the given formatter.

impl Display for Weekday

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

Formats the value using the given formatter.

impl FromStr for Weekday

type Err = InvalidVariant

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

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

impl Hash for Weekday

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Weekday

fn eq(&self, other: &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 !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl SmartDisplay for Weekday

type Metadata = WeekdayMetadata

User-provided metadata type.

fn metadata(&self, _: FormatterOptions) -> Metadata<'_, Self>

Compute any information needed to format the value. This must, at a minimum, determine the width of the value before any padding is added by the formatter.

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

Format the value using the given formatter. This is the same as Display::fmt.

fn fmt_with_metadata( &self, f: &mut Formatter<'_>, _metadata: Metadata<'_, Self> ) -> Result<(), Error>

Format the value using the given formatter and metadata. The formatted output should have the width indicated by the metadata. This is before any padding is added by the formatter.
