Structure_Differentiation5.9.0
AnyDerivative
A type-erased derivative value.
@frozen struct AnyDerivativeThe AnyDerivative type forwards its operations to an arbitrary underlying base derivative value conforming to Differentiable and AdditiveArithmetic, hiding the specifics of the underlying value.
