Trait BoxedMapped 

pub trait BoxedMapped { }

Marker types for guards that are mapped by first being boxed (because they make no guarantees that their target reference can be detached from their location in memory.) Technically this could be anything, but the operation only really makes sense for guards, in order to return the mapping from a function.
