public struct AnyDerivative : EuclideanDifferentiable & AdditiveArithmetic

A type-erased derivative value.

The AnyDerivative type forwards its operations to an arbitrary underlying base derivative value conforming to Differentiable and AdditiveArithmetic, hiding the specifics of the underlying value.

  • The underlying base value.

    Declaration

    public var base: Any { get }
  • Creates a type-erased derivative from the given derivative.
