Struct Simulator 

pub struct Simulator<E> { /* private fields */ }

Stateless RK4 stepper over an immutable vehicle, force model and settings.

Motor ignition, each thrust knot and burnout split integration intervals so no step straddles a motor discontinuity. Mass is evaluated analytically at every RK stage. Collision detection and terrain termination belong to the host application.

Implementations

impl<E: ForceModel> Simulator<E>

pub fn new( rocket: Rocket, forces: E, settings: IntegratorSettings, ) -> Result<Self>

Create a reusable simulator, validating settings before any integration.

pub fn rocket(&self) -> &Rocket

The vehicle configuration needed alongside a snapshot to resume a flight.

pub fn forces(&self) -> &E

Current environmental force model.

pub fn forces_mut(&mut self) -> &mut E

Access the environment to update externally sampled weather between steps.

pub fn settings(&self) -> IntegratorSettings

Validated integrator settings.

pub fn step( &self, state: &FlightState, duration_s: f64, control: ControlInput, ) -> Result<StepResult>

Advance using an externally supplied command, held fixed for the requested duration. Call at a fixed cadence to obtain repeatable controller and integration behavior.

pub fn step_guided<G: Guidance + ?Sized>( &self, state: &FlightState, duration_s: f64, guidance: &mut G, ) -> Result<StepResult>

Evaluate guidance once, then advance under its held command. Invalid state/duration is rejected before calling guidance. A later model error leaves the input flight state unchanged but does not roll back the controller.

Trait Implementations

impl<E: Clone> Clone for Simulator<E>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E: Debug> Debug for Simulator<E>

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

Formats the value using the given formatter.
