fn to_superset(&self) -> PointBase<N2, D, SB>

The inclusion map: converts self to the equivalent element of its superset.

fn is_in_subset(m: &PointBase<N2, D, SB>) -> bool

Checks if element is actually part of the subset Self (and can be converted to it).

unsafe fn from_superset_unchecked(m: &PointBase<N2, D, SB>) -> Self

Use with care! Same as self.to_superset but without any property checks. Always succeeds.

fn from_superset(element: &T) -> Option<Self>

The inverse inclusion map: attempts to construct self from the equivalent element of its superset.
