std::type_index

Member functions

type_index::type_index

type_index::operator= type_index::operator!= type_index::operator< type_index::operator<= type_index::operator>

type_index::hash_code

type_index::name

 

Defined in header <typeindex>
struct hash<type_index>;		(since C++11)

The template specialization of std::hash for std::type_index allows users to obtain hashes of objects of type std::type_index.

Return value

Effectively returns the same value as hash_code().
