public struct AnyDerivative : Differentiable & 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.
