Enum ScaleKind 

pub enum ScaleKind {
    JdTt,
    MjdTt,
    Tdb,
    Tai,
    Tcg,
    Tcb,
    GpsDays,
    Ut1,
    Unix,
}

Identifies a time scale or scalar encoding for dispatch.

ScaleKind is the Rust-native counterpart to C ABI scale identifiers. FFI adapters map their own integer discriminants to ScaleKind and then delegate all conversion logic to time_tt_from_scalar and time_tt_to_scalar rather than reimplementing the dispatch matrix.

Variants

JdTt

Julian Day (TT) — equivalently Julian Ephemeris Date (JDE). Value in days.

MjdTt

Modified Julian Day on the TT axis. Value in days.

Tdb

Barycentric Dynamical Time, Julian days on the TDB axis.

Tai

International Atomic Time, Julian days on the TAI axis.

Tcg

Geocentric Coordinate Time, Julian days on the TCG axis.

Tcb

Barycentric Coordinate Time, Julian days on the TCB axis.

GpsDays

GPS days since GPS_EPOCH_JD_TAI on the TAI axis.

The unit is Julian days (not GPS seconds). A value of 1.0 represents one Julian day (86 400 s) elapsed since the GPS epoch. This is distinct from conventional GPS time which is expressed in integer seconds or (week, seconds-of-week). Divide by 86 400 to convert from GPS seconds to this representation.

Ut1

Universal Time UT1, Julian days on the UT1 axis.

Unix

Unix / POSIX time in seconds since 1970-01-01T00:00:00 UTC.

Trait Implementations

impl Clone for ScaleKind

fn clone(&self) -> ScaleKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScaleKind

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

Formats the value using the given formatter.

impl PartialEq for ScaleKind

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