Struct PlanetShape 

pub struct PlanetShape {
    pub name: &'static str,
    pub mu: f64,
    pub r_eq: f64,
    pub r_pol: f64,
    pub flat_coeff: f64,
}

Planetary shape parameters (reference ellipsoid).

Mirrors JEOD’s Planet struct from planet.hh. The mu field stores the geodetic standard gravitational parameter (e.g., WGS84 for Earth). Gravity models carry their own mu in GravitySource which may differ slightly.

Fields

name: &'static str

Planet name.

mu: f64

Gravitational parameter (m^3/s^2).

r_eq: f64

Mean equatorial radius (m).

r_pol: f64

Mean polar radius (m).

flat_coeff: f64

Flattening coefficient: f = (r_eq - r_pol) / r_eq.

Implementations

impl PlanetShape

pub fn flat_inv(&self) -> f64

Inverse flattening (e.g., 298.257223563 for Earth).

pub fn e_ellipsoid(&self) -> f64

Ellipsoid eccentricity: e = sqrt(2f - f^2).

pub fn e_ellip_sq(&self) -> f64

Square of ellipsoid eccentricity.

pub fn mu_typed(&self) -> GravParam<SelfPlanet>

Gravitational parameter as a typed GravParam<astrodyn_quantities::frame::SelfPlanet> (m³/s²).

Returns the planet-erased (astrodyn_quantities::frame::SelfPlanet) form because PlanetShape is the dynamic per-planet record carried by the runner — the planet identity is determined by which entity holds the shape, not by the static type. Mission code that knows the planet at compile time can either reach for the curated mu_*() constants in astrodyn::recipes::constants (which return planet-pinned GravParam<P> values) or relabel at the call site via mu_typed().relabel::<P>().

pub fn r_eq_typed( &self, ) -> Quantity<dyn Dimension<Kind = dyn Kind, T = Z0, L = PInt<UInt<UTerm, B1>>, N = Z0, Th = Z0, M = Z0, J = Z0, I = Z0>, dyn Units<f64, thermodynamic_temperature = kelvin, time = second, electric_current = ampere, amount_of_substance = mole, mass = kilogram, luminous_intensity = candela, length = meter>, f64>

Equatorial radius as a typed uom::si::f64::Length (meters).

Additive typed accessor introduced by Phase 1 of the type-system refactor (issue #101). Wraps the existing r_eq f64 field; the underlying field is unchanged.

pub fn r_pol_typed( &self, ) -> Quantity<dyn Dimension<Kind = dyn Kind, T = Z0, L = PInt<UInt<UTerm, B1>>, N = Z0, Th = Z0, M = Z0, J = Z0, I = Z0>, dyn Units<f64, thermodynamic_temperature = kelvin, time = second, electric_current = ampere, amount_of_substance = mole, mass = kilogram, luminous_intensity = candela, length = meter>, f64>

Polar radius as a typed uom::si::f64::Length (meters).

Additive typed accessor introduced by Phase 1 of the type-system refactor (issue #101). Wraps the existing r_pol f64 field; the underlying field is unchanged.
