pub enum ObjectLifetimeDefault { Ambiguous, Specific(Region), }
Default region to use for the bound of objects that are
supplied as the value for this type parameter. This is derived

annotations appearing in the type definition. If
this is None
, then the default is inherited from the
surrounding context. See RFC #599 for details.
