Trait SpheroidalUnits 

pub trait SpheroidalUnits<T: SpheroidalScalar>: AngleUnit {
    const PERIOD: T;
    const HALF_PERIOD: T;
    const QUARTER_PERIOD: T;
}

Canonical angular constants for a spheroidal unit and scalar pair.

Mirrors constants_on_spheroid<CoordinateType, Units> from util/normalize_spheroidal_coordinates.hpp:34-145.

Required Associated Constants

const PERIOD: T

One complete longitude turn.

const HALF_PERIOD: T

The positive antimeridian.

const QUARTER_PERIOD: T

The positive pole latitude in the equatorial convention.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
