Struct DP45

pub struct DP45 {
    pub tol: f64,

Dormand-Prince 5(4) method

This is an adaptive step size integrator based on a 5th order Runge-Kutta method with 4th order embedded error estimation.

Member variables

• tol: The tolerance for the estimated error.
• safety_factor: The safety factor for the step size adjustment.
• min_step_size: The minimum step size.
• max_step_size: The maximum step size.
• max_step_iter: The maximum number of iterations per step.

Fields

tol: f64

safety_factor: f64

min_step_size: f64

max_step_size: f64

max_step_iter: usize

Implementations

impl DP45

pub fn new( tol: f64, safety_factor: f64, min_step_size: f64, max_step_size: f64, max_step_iter: usize, ) -> Self

Trait Implementations

impl Archive for DP45

where f64: Archive, usize: Archive,

const COPY_OPTIMIZATION: CopyOptimization<Self>

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

type Archived = ArchivedDP45

The archived representation of this type.

type Resolver = DP45Resolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)

Creates the archived version of this value at the given position and writes it to the given output.

impl ButcherTableau for DP45

const C: &'static [f64]

const A: &'static [&'static [f64]]

const BU: &'static [f64]

const BE: &'static [f64]

fn tol(&self) -> f64

fn safety_factor(&self) -> f64

fn min_step_size(&self) -> f64

fn max_step_size(&self) -> f64

fn max_step_iter(&self) -> usize

impl Clone for DP45

fn clone(&self) -> DP45

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DP45

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

Formats the value using the given formatter.

impl Default for DP45

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DP45

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<__D: Fallible + ?Sized> Deserialize<DP45, __D> for Archived<DP45>

where f64: Archive, <f64 as Archive>::Archived: Deserialize<f64, __D>, usize: Archive, <usize as Archive>::Archived: Deserialize<usize, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<DP45, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl<__S: Fallible + ?Sized> Serialize<__S> for DP45

where f64: Serialize<__S>, usize: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.

impl Serialize for DP45

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
