Struct product_os_async_executor::Days

pub struct Days(/* private fields */);

A duration in calendar days.

This is useful because when using TimeDelta it is possible that adding TimeDelta::days(1) doesn’t increment the day value as expected due to it being a fixed number of seconds. This difference applies only when dealing with DateTime<TimeZone> data types and in other cases TimeDelta::days(n) and Days::new(n) are equivalent.

Implementations

impl Days

pub const fn new(num: u64) -> Days

Construct a new Days from a number of days

Trait Implementations

impl<Tz> Add<Days> for DateTime<Tz>

where Tz: TimeZone,

Add Days to NaiveDateTime.

Panics

Panics if:

• The resulting date would be out of range.
• The local time at the resulting date does not exist or is ambiguous, for example during a daylight saving time transition.

Strongly consider using DateTime<Tz>::checked_sub_days to get an Option instead.

type Output = DateTime<Tz>

The resulting type after applying the + operator.

fn add(self, days: Days) -> <DateTime<Tz> as Add<Days>>::Output

Performs the + operation.

impl Add<Days> for NaiveDate

Add Days to NaiveDate.

Panics

Panics if the resulting date would be out of range. Consider using NaiveDate::checked_add_days to get an Option instead.

type Output = NaiveDate

The resulting type after applying the + operator.

fn add(self, days: Days) -> <NaiveDate as Add<Days>>::Output

Performs the + operation.

impl Add<Days> for NaiveDateTime

Add Days to NaiveDateTime.

Panics

Panics if the resulting date would be out of range. Consider using checked_add_days to get an Option instead.

type Output = NaiveDateTime

The resulting type after applying the + operator.

fn add(self, days: Days) -> <NaiveDateTime as Add<Days>>::Output

Performs the + operation.

impl Clone for Days

fn clone(&self) -> Days

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Days

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

Formats the value using the given formatter.

impl Hash for Days

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 Ord for Days

fn cmp(&self, other: &Days) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Days

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

impl PartialOrd for Days

fn partial_cmp(&self, other: &Days) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl<Tz> Sub<Days> for DateTime<Tz>

where Tz: TimeZone,

Subtract Days from DateTime.

Panics

Panics if:

• The resulting date would be out of range.
• The local time at the resulting date does not exist or is ambiguous, for example during a daylight saving time transition.

Strongly consider using DateTime<Tz>::checked_sub_days to get an Option instead.

type Output = DateTime<Tz>

The resulting type after applying the - operator.

fn sub(self, days: Days) -> <DateTime<Tz> as Sub<Days>>::Output

Performs the - operation.

impl Sub<Days> for NaiveDate

Subtract Days from NaiveDate.

Panics

Panics if the resulting date would be out of range. Consider using NaiveDate::checked_sub_days to get an Option instead.

type Output = NaiveDate

The resulting type after applying the - operator.

fn sub(self, days: Days) -> <NaiveDate as Sub<Days>>::Output

Performs the - operation.

impl Sub<Days> for NaiveDateTime

Subtract Days from NaiveDateTime.

Panics

Panics if the resulting date would be out of range. Consider using checked_sub_days to get an Option instead.

type Output = NaiveDateTime

The resulting type after applying the - operator.

fn sub(self, days: Days) -> <NaiveDateTime as Sub<Days>>::Output

Performs the - operation.
