Enum ScaleKind

    JdTt,
    MjdTt,

}

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.

Variant names follow the <Format><Scale> convention: the prefix names the encoding format (e.g. Jd = Julian Day, Mjd = Modified Julian Day) and the suffix names the time scale (e.g. Tt, Tai, Tdb).

Variants

JdTt

Julian Day on the TT axis (equivalently: Julian Ephemeris Date). Value in days.

MjdTt

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

JdTdb

Julian Day on the TDB axis. Value in days.

JdTai

Julian Day on the TAI axis. Value in days.

JdTcg

Julian Day on the TCG axis. Value in days.

JdTcb

Julian Day on the TCB axis. Value in days.

JdGps

Julian Day offset from the GPS epoch, 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 encoding.

JdUt1

Julian Day on the UT1 axis. Value in days.

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.
