Implementations

impl Drag

pub fn earth_exp(almanac: &Almanac) -> Result<Arc<Self>, DynamicsError>

Common exponential drag model for the Earth

pub fn std_atm1976(almanac: &Almanac) -> Result<Arc<Self>, DynamicsError>

Drag model which uses the standard atmosphere 1976 model for atmospheric density

Trait Implementations

impl Clone for Drag

fn clone(&self) -> Drag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Drag

impl Debug for Drag

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

Formats the value using the given formatter.

impl DerefToPyAny for Drag

impl<'de> Deserialize<'de> for Drag

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Drag

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

Formats the value using the given formatter.

impl ForceModel for Drag

fn estimation_index(&self) -> Option<usize>

If a parameter of this force model is stored in the spacecraft state, then this function should return the index where this parameter is being affected

fn eom( &self, ctx: &Spacecraft, almanac: &Almanac, ) -> Result<Vector3<f64>, DynamicsError>

Defines the equations of motion for this force model from the provided osculating state.

fn gradient( &self, _osc_ctx: &Spacecraft, _almanac: &Almanac, ) -> Result<(Vector3<f64>, Matrix4x3<f64>), DynamicsError>

Force models must implement their partials, although those will only be called if the propagation requires the computation of the STM. The osc_ctx is the osculating context, i.e. it changes for each sub-step of the integrator. The last row corresponds to the partials of the parameter of this force model wrt the position, i.e. this only applies to conservative forces.

type Error = PyClassGuardError<'a, 'py>

const RAW_DOC: &'static CStr = /// `Drag` implements all three drag models.

Docstring for the class provided on the struct or enum.

const DOC: &'static CStr

type Layout = <<Drag as PyClassImpl>::BaseNativeType as PyClassBaseType>::Layout<Drag>

Description of how this class is laid out in memory

type BaseType = PyAny

Base class

type ThreadChecker = NoopThreadChecker

This handles following two situations:

type Inventory = Pyo3MethodsInventoryForDrag

type PyClassMutability = <<PyAny as PyClassBaseType>::PyClassMutability as PyClassMutability>::MutableChild

Immutable or mutable

type Dict = PyClassDummySlot

Specify this class has #[pyclass(dict)] or not.

type WeakRef = PyClassDummySlot

Specify this class has #[pyclass(weakref)] or not.

type BaseNativeType = PyAny

The closest native ancestor. This is PyAny by default, and when you declare #[pyclass(extends=PyDict)], it’s PyDict.

fn items_iter() -> PyClassItemsIter

fn lazy_type_object() -> &'static LazyTypeObject<Self>

fn dict_offset() -> Option<PyObjectOffset>
