Struct UtcInstant 

pub struct UtcInstant { /* private fields */ }

UTC instant represented as unix microseconds.

Implementations

impl UtcInstant

pub fn from_unix_microseconds(unix_microseconds: i64) -> Self

Construct from unix microseconds.

pub fn from_utc( year: i32, month: i32, day: i32, hour: i32, minute: i32, second: i32, microsecond: i32, ) -> Option<Self>

Construct from UTC calendar fields.

This type stores a POSIX-like Unix microsecond count, so leap-second labels cannot be represented distinctly from the following midnight.

pub fn unix_microseconds(self) -> i64

Unix microseconds.

pub fn time_scales(self) -> TimeScales

Resolve the precise split-Julian-date time scales (UT1/TT/TDB) for this UTC instant, via the parity-critical TimeScales::from_utc path.

Exposed so a Rust or Python consumer can reach the precise time scales for an instant given only its unix-microsecond UTC stamp, without restating the calendar breakdown. The numerics are unchanged from the internal pass-finder use.

Trait Implementations

impl Clone for UtcInstant

fn clone(&self) -> UtcInstant

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for UtcInstant

impl Debug for UtcInstant

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

Formats the value using the given formatter.

impl Eq for UtcInstant

impl Ord for UtcInstant

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

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

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