impl Weekday

pub const fn previous(self) -> Weekday

Get the previous weekday.

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

pub const fn next(self) -> Weekday

Get the next weekday.

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

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

Get n-th next day.

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