Enum astrolabe::DateUnit

pub enum DateUnit {
    Year,
    Month,
    Day,
}

Date units for functions like Date::get or Date::apply.

Variants

Year

Month

Note: When used in the Date::apply function, this unit adds or removes calendar months, not 30 days.

let date = Date::from_ymd(1970, 1, 31).unwrap();
assert_eq!("1970-02-28", date.apply(1, DateUnit::Month).unwrap().format("yyyy-MM-dd"));
assert_eq!("1970-03-31", date.apply(2, DateUnit::Month).unwrap().format("yyyy-MM-dd"));
assert_eq!("1970-04-30", date.apply(3, DateUnit::Month).unwrap().format("yyyy-MM-dd"));

impl Clone for DateUnit

fn clone(&self) -> DateUnit

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DateUnit

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

impl PartialEq<DateUnit> for DateUnit

fn eq(&self, other: &DateUnit) -> 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.
