Enum TimeScale 

pub enum TimeScale {
    UTC,
    TAI,
    TT,
    TDB,
    ET,
    GPST,
    GST,
    BDT,
    QZSST,
}

Time scales supported by Graphcal.

Each variant maps 1:1 to a hifitime::TimeScale variant. UTC is the default for civil datetime values.

Variants

UTC

Coordinated Universal Time — default for civil use.

TAI

International Atomic Time — continuous, the internal reference.

TT

Terrestrial Time — TAI + 32.184 s, used in orbital mechanics.

TDB

Barycentric Dynamical Time — used for solar system ephemerides.

ET

Ephemeris Time (NAIF/SPICE variant, ≈ TDB).

GPST

GPS Time — TAI − 19 s.

GST

Galileo System Time.

BDT

BeiDou Time.

QZSST

QZSS Time.

Implementations

impl TimeScale

pub const ALL_NAMES: &[&str]

All supported time scale names, for error messages and validation.

pub const fn is_utc(self) -> bool

Returns true if this is the default civil time scale (UTC).

pub const fn name(self) -> &'static str

Returns the string name of this time scale.

pub const fn to_hifitime(self) -> TimeScale

Convert to the corresponding hifitime::TimeScale.

pub const fn from_hifitime(ts: TimeScale) -> Self

Convert from hifitime::TimeScale.

Trait Implementations

impl Clone for TimeScale

fn clone(&self) -> TimeScale

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TimeScale

impl Debug for TimeScale

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

Formats the value using the given formatter.

impl Display for TimeScale

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

Formats the value using the given formatter.

impl Eq for TimeScale

impl FromStr for TimeScale

type Err = ParseTimeScaleError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for TimeScale

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 TimeScale

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