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

self
is actually part of its subset T

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.
