Trait DynamicsModel 

pub trait DynamicsModel<const N: usize, const P: usize> {
    const NAME: &'static str;

    // Required method
    fn rhs(
        &self,
        time: f64,
        state: &[f64; N],
        parameters: &[f64; P],
        derivative: &mut [f64; N],
    ) -> Result<()>;

    // Provided method
    fn validate(
        &self,
        _time: f64,
        _state: &[f64; N],
        _parameters: &[f64; P],
    ) -> Result<()> { ... }
}

An evaluated first-order dynamics model with N states and P parameters.

Implementations must not allocate in Self::rhs. The integrator validates dimensions and finite inputs before calling the model.

Required Associated Constants

const NAME: &'static str

Stable model name used in diagnostics.

Required Methods

fn rhs( &self, time: f64, state: &[f64; N], parameters: &[f64; P], derivative: &mut [f64; N], ) -> Result<()>

Evaluates dstate/dt into caller-owned storage.

Errors

Returns an error when the dynamics are singular or cannot be evaluated.

Provided Methods

fn validate( &self, _time: f64, _state: &[f64; N], _parameters: &[f64; P], ) -> Result<()>

Validates state and parameter domains before a propagation.

The default accepts every finite state and parameter vector.

Errors

Returns an error when the initial state or parameters are outside the model’s physical domain.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
