pub fn intrinsic_derivative_bounds2(
curve: &Intrinsic2,
a: Scalar,
b: Scalar,
) -> Option<CurveDerivativeBounds>Expand description
Certified derivative suprema of a 2D intrinsic curve over [a, b] of
its arc length; None outside [0, length] or for a law with no
closed-form bound. third is infinite over a span with a seam of the
law strictly inside.
