Checks if
self is actually part of its subset T (and can be converted to it).§fn to_subset_unchecked(&self) -> SS

Use with care! Same as
self.to_subset but without any property checks. Always succeeds.§fn from_subset(element: &SS) -> SP

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