Struct Interval 

pub struct Interval {
    pub count: i64,
    pub unit: IntervalUnit,
}

An interval value for date arithmetic.

Fields

count: i64

The count (can be negative).

unit: IntervalUnit

The unit.

Implementations

impl Interval

pub const fn new(count: i64, unit: IntervalUnit) -> Self

Create a new interval.

pub fn add_to_date(&self, date: NaiveDate) -> Option<NaiveDate>

Add this interval to a date.

Trait Implementations

impl Clone for Interval

fn clone(&self) -> Interval

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Interval

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

Formats the value using the given formatter.

impl Hash for Interval

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 Interval

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
