pub struct BoxedGuidance(pub Box<dyn Guidance>);Expand description
Owned, type-erased guidance handle for heterogeneous decorator chains.
A newtype rather than Box<dyn Guidance> so it cannot collide with the
blanket closure implementations.

The inverse inclusion map: attempts to construct

superset. Read moreSource§fn is_in_subset(&self) -> bool

Checks if
self is actually part of its subset T (and can be converted to it).Source§fn to_subset_unchecked(&self) -> SS
fn to_subset_unchecked(&self) -> SS
Use with care! Same as
self.to_subset but without any property checks. Always succeeds.Source§fn from_subset(element: &SS) -> SP
fn from_subset(element: &SS) -> SP
The inclusion map: converts
self to the equivalent element of its superset.
