Enum astrolabe::DateTimeUnit

pub enum DateTimeUnit {
    Year,
    Month,
    Day,
    Hour,
    Min,
    Sec,
    Centis,
    Millis,

}

Date and time units for functions like DateTime::get or DateTime::apply.

Variants

Year

Month

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

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

Trait Implementations

impl Clone for DateTimeUnit

fn clone(&self) -> DateTimeUnit

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DateTimeUnit

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

Formats the value using the given formatter.

impl PartialEq<DateTimeUnit> for DateTimeUnit

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