The inverse inclusion map: attempts to construct
self
from the equivalent element of its
superset. Read more§fn is_in_subset(&self) -> bool

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

fn from_subset(element: &SS) -> SP
The inclusion map: converts
self
to the equivalent element of its superset.
