Struct RataDie

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

The Rata Die, or R.D.: number of days since January 1, 1 CE.

The primary definition of this type is in the calendrical_calculations crate.

See: https://en.wikipedia.org/wiki/Rata_Die

Typically, one should obtain RataDies from other calendrical code, rather than constructing them from integers. The valid range for direct construction is deliberately not documented as it may change.

Implementations

impl RataDie

pub const fn new(fixed_date: i64) -> Self

Create a RataDie

Typically, one should obtain RataDies from other calendrical code, rather than constructing them from integers. The valid range for direct construction is deliberately not documented as it may change.

pub const fn to_i64_date(self) -> i64

Convert this to an i64 value representing the RataDie

pub const fn until(self, rhs: Self) -> i64

Calculate the number of days between two RataDie in a const-friendly way

pub const fn add(self, rhs: i64) -> Self

Adds a number of days to this RataDie in a const-friendly way

Trait Implementations

impl Add<i64> for RataDie

Shift a RataDie N days into the future

type Output = RataDie

The resulting type after applying the + operator.

fn add(self, rhs: i64) -> Self::Output

Performs the + operation.

impl AddAssign<i64> for RataDie

fn add_assign(&mut self, rhs: i64)

Performs the += operation.

impl Clone for RataDie

fn clone(&self) -> RataDie

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RataDie

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

Formats the value using the given formatter.

impl Hash for RataDie

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 Ord for RataDie

fn cmp(&self, other: &RataDie) -> 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,

Restrict a value to a certain interval.

impl PartialEq for RataDie

fn eq(&self, other: &RataDie) -> 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 PartialOrd for RataDie

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Sub<i64> for RataDie

Shift a RataDie N days into the past

type Output = RataDie

The resulting type after applying the - operator.

fn sub(self, rhs: i64) -> Self::Output

Performs the - operation.

impl Sub for RataDie

Calculate the number of days between two RataDie

type Output = i64

The resulting type after applying the - operator.

fn sub(self, rhs: Self) -> Self::Output

Performs the - operation.

impl SubAssign<i64> for RataDie

fn sub_assign(&mut self, rhs: i64)

Performs the -= operation.
