Struct DrydenGenerator 

pub struct DrydenGenerator { /* private fields */ }

A seeded Dryden turbulence generator that advances along the flight path.

The state is normalized, so the intensities and scale lengths may change from one step to the next (for example with altitude); within a step they are held constant. Draws come from a SeededRng in a fixed order (u, then two for v, then two for w), so the same seed and the same steps give bit-identical gusts on one platform. (Across platforms the math library’s exp and ln may differ in the last bit.)

It serializes as its generator and state, so a run can be checkpointed and resumed; a non-finite state is rejected when deserialized.

Implementations

impl DrydenGenerator

pub fn new(seed: u64) -> Self

A generator whose initial state is drawn from the stationary distribution using seed.

pub fn gust_m_s(&self, parameters: &DrydenParameters) -> DVec3

The current gust (u, v, w) for parameters, m/s.

pub fn advance( &mut self, distance_m: f64, parameters: &DrydenParameters, ) -> Result<DVec3, AtmosError>

Moves distance_m along the path through turbulence described by parameters, and returns the gust there.

Errors

AtmosError::Domain if the distance is negative or not finite.

Trait Implementations

impl Clone for DrydenGenerator

fn clone(&self) -> DrydenGenerator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DrydenGenerator

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DrydenGenerator

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DrydenGenerator

fn eq(&self, other: &DrydenGenerator) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for DrydenGenerator

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
