<typeindex>

Include the standard header <typeindex> to define a class and function that support the indexing of objects of class type_info.

Syntax

#include <typeindex>

Remarks

The hash Structure defines a hash function that's suitable for mapping values of type type_index to a distribution of index values.

The type_index class wraps a pointer to a type_info object to assist in indexing.
