Trait Diffusion 

pub trait Diffusion
where
    Self: Clone + Debug,
{
    type Balance: Diffusive;

    // Required methods
    fn potential(
        &self,
        gradient: &DiffusionGradient<Self>,
    ) -> Result<Quantity<<Self::Balance as Diffusive>::EnergyDensity>, ConstitutiveError>;
    fn flux(
        &self,
        gradient: &DiffusionGradient<Self>,
    ) -> Result<DiffusionFlux<Self>, ConstitutiveError>;
    fn tangent(
        &self,
        gradient: &DiffusionGradient<Self>,
    ) -> Result<DiffusionTangent<Self>, ConstitutiveError>;
}

Required methods for diffusion constitutive models.

The flux is $-\kappa\nabla\phi$ for a field $\phi$, so that the tangent is negative, and the potential is the energy density whose derivative with respect to the gradient is the negative flux.

Required Associated Types

type Balance: Diffusive

The balance law the flux enters.

Required Methods

fn potential( &self, gradient: &DiffusionGradient<Self>, ) -> Result<Quantity<<Self::Balance as Diffusive>::EnergyDensity>, ConstitutiveError>

Calculates and returns the potential.

fn flux( &self, gradient: &DiffusionGradient<Self>, ) -> Result<DiffusionFlux<Self>, ConstitutiveError>

Calculates and returns the flux.

fn tangent( &self, gradient: &DiffusionGradient<Self>, ) -> Result<DiffusionTangent<Self>, ConstitutiveError>

Calculates and returns the tangent to the flux.

Dyn Compatibility

This trait is not dyn compatible.

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