std::type_index

Introduced in C++11, std::type_index is a wrapper class around a std::type_info object, that can be used as index in associative and unordered associative containers.

Ruby does not have a concept of a type_index. Therefore, Rice wraps std::type_index which means that data is not copied between C++ and Ruby.

Ruby API

The Ruby API for std::type_index is:

• TypeIndex#hash_code (see hash_code)

• TypeIndex#name (see name)
