pub fn banked_breaks(curve: &Banked3, k: usize) -> Vec<Scalar> ⓘExpand description
elevated_breaks of a banked curve’s point path, plus the seams of
its pivot law (its rate may jump there). The cant law moves only the
section frame, not the point, so its seams are not named – except
where a held-rail pivot piece derives the point from the cant (#279):
the cant’s seams there are the pivot’s.
