Classes
class	Hash< T >
	Hash function class. The default definition is for primitives. Non-primitives used to hash entries on hash tables will need a specialized version. More...
struct	Hash< std::nullptr_t >
	Hashing of nullptr, always 0. More...
struct	Hash< void * >
	Hashing of pointers, treat as unsigned integer. More...
struct	Hash< bool >
	Hashing of integral type: bool. More...
struct	Hash< char >
	Hashing of integral type: char. More...
struct	Hash< int32_t >
	Hashing of integral type: int32_t. More...
struct	Hash< int64_t >
	Hashing of integral type: int64_t. More...
struct	Hash< uint32_t >
	Hashing of integral type: uint32_t. More...
