Struct ModifiedJulianDate 

pub struct ModifiedJulianDate { /* private fields */ }

The Modified Julian Day (MJD) representation of any given date.

Implementations

impl ModifiedJulianDate

pub const fn from_time_since_epoch(time_since_epoch: Days) -> Self

Constructs a new MJD directly from some duration since the MJD epoch, November 17 1858.

pub const fn time_since_epoch(&self) -> Days

Returns the time since the MJD epoch of this day.

pub fn from_date(date: Date) -> Self

Constructs a modified Julian date from some given calendar date.

pub fn into_date(&self) -> Date

Converts this modified Julian date into the equivalent “universal” calendar date.

pub fn from_historic_date( year: i32, month: Month, day: u8, ) -> Result<Self, InvalidHistoricDate>

Creates a Date based on a year-month-day date in the historic calendar.

pub fn from_gregorian_date( year: i32, month: Month, day: u8, ) -> Result<Self, InvalidGregorianDate>

Creates a Date based on a year-month-day date in the proleptic Gregorian calendar.

pub fn from_julian_date( year: i32, month: Month, day: u8, ) -> Result<Self, InvalidJulianDate>

Creates a Date based on a year-month-day date in the proleptic Julian calendar.

Trait Implementations

impl Clone for ModifiedJulianDate

fn clone(&self) -> ModifiedJulianDate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ModifiedJulianDate

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

Formats the value using the given formatter.

impl From<Date> for ModifiedJulianDate

fn from(value: Date) -> Self

Converts to this type from the input type.

impl From<ModifiedJulianDate> for Date

fn from(value: ModifiedJulianDate) -> Self

Converts to this type from the input type.

impl Hash for ModifiedJulianDate

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 ModifiedJulianDate

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

fn eq(&self, other: &ModifiedJulianDate) -> 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 ModifiedJulianDate

fn partial_cmp(&self, other: &ModifiedJulianDate) -> 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.
