Struct OrbitalEngine 

pub struct OrbitalEngine { /* private fields */ }

Unified orbital engine implementing DemoEngine.

This replaces the old KeplerOrbitDemo + EddDemo pattern with a proper DemoEngine implementation that:

• Loads from YAML
• Produces deterministic states
• Supports TUI/WASM parity verification

Implementations

impl OrbitalEngine

pub fn kepler_config(&self) -> KeplerConfig

Convert internal config to KeplerConfig for legacy compatibility.

This allows the new YAML-first engine to work with code expecting the old KeplerConfig type.

Trait Implementations

impl Clone for OrbitalEngine

fn clone(&self) -> OrbitalEngine

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OrbitalEngine

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

Formats the value using the given formatter.

impl DemoEngine for OrbitalEngine

type Config = OrbitConfig
