UniqueHashFunction
is a concept for a hash function with unique hash values. An instance hash
for a model of the UniqueHashFunction
concept is a function object. It maps objects of its domain type Key
to the integral image type std::size_t
. The image values have to be unique for all keys in the domain type Key
.
