Struct Period 

pub struct Period {
    pub num: i32,
    pub unit: Unit,
}

A signed span of calendar time, e.g. 3 months or -2 weeks.

Days/Weeks add a fixed number of days. Months/Years are calendar arithmetic: the day-of-month is preserved where possible and clamped to the last day of the target month otherwise (so Jan 31 + 1 month = Feb 28, and Feb 29 + 1 year = Feb 28 in a non-leap year).

Fields

num: i32

unit: Unit

Implementations

impl Period

pub fn days(n: i32) -> Self

n days.

pub fn weeks(n: i32) -> Self

n weeks (7 days each).

pub fn months(n: i32) -> Self

n calendar months.

pub fn years(n: i32) -> Self

n calendar years.

Trait Implementations

impl Add<Period> for Date

type Output = Date

The resulting type after applying the + operator.

fn add(self, period: Period) -> Date

Performs the + operation.

impl Clone for Period

fn clone(&self) -> Period

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Period

impl Debug for Period

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

Formats the value using the given formatter.

impl Display for Period

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

Formats the value using the given formatter.

impl Eq for Period

impl Hash for Period

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 Period

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

impl StructuralPartialEq for Period

impl Sub<Period> for Date

type Output = Date

The resulting type after applying the - operator.

fn sub(self, period: Period) -> Date

Performs the - operation.
