Trait IVPStepper 

pub trait IVPStepper<D: Dimension>: Sized
where
    DefaultAllocator: Allocator<Self::Field, D>,
{
    type Error: Error + From<IVPError>;
    type Field: ComplexField + Copy;
    type RealField: RealField;
    type UserData: Clone;

    // Required methods
    fn step(&mut self) -> Step<Self::RealField, Self::Field, D, Self::Error>;
    fn time(&self) -> Self::RealField;
}

Implementing this trait is providing the main functionality of an initial value problem solver. This should be used only when implementing an IVPSolver, users should use the solver via the IVPSolver trait’s interface.

Required Associated Types

type Error: Error + From<IVPError>

Error type. IVPError must be able to convert to the error type.

type Field: ComplexField + Copy

The field, complex or real, that the solver is operating on.

type RealField: RealField

The real field associated with the solver’s Field.

type UserData: Clone

Arbitrary data provided by the user for the derivative function It must be clone because for any intermediate time steps (e.g. in runge-kutta) gives the derivative function a clone of the params: only normal time steps get to update the internal UserData state

Required Methods

fn step(&mut self) -> Step<Self::RealField, Self::Field, D, Self::Error>

Step forward in the solver. The solver may request a step be redone, signal that the solution is finished, or give the value of the next solution value.

fn time(&self) -> Self::RealField

Get the current time of the solver.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
