Detailed Description

template<typename Type, Type Empty, Type Deleted = Empty>
struct int_hash< Type, Empty, Deleted >

Hasher for integer type Type in which Empty is a spare value that can be
used to mark empty slots.  If Deleted != Empty then Deleted is another
spare value that can be used for deleted slots; if Deleted == Empty then
hash table entries cannot be deleted.
