Trait TimeScale 

pub trait TimeScale:

    + Copy
    + Clone
    + Eq
    + PartialEq
    + Debug {

}

Marker trait for GNSS / atomic time scales.

This trait is sealed and cannot be implemented outside this crate.

Each scale defines:

• TimeScale::NAME — short name
• TimeScale::OFFSET_TO_TAI — conversion to TAI

Required Associated Constants

const NAME: &'static str

Short ASCII name of the scale, used in Display/debug output.

const OFFSET_TO_TAI: OffsetToTai

Offset relative to TAI:

STRICT CONTRACT: T_tai = T_self + offset

For contextual scales (UTC, GLONASS), leap-second handling is required.

const EPOCH_CIVIL: CivilDate

Civil date of the scale’s epoch (where Time<S>::EPOCH == 0 ns)

const DISPLAY_STYLE: DisplayStyle

Time display format

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
