Detailed Documentation

Type information for a type system without inheritance; instances have exactly one type not related to any other type.

Supports three functions, ov::is_type<Type>, ov::as_type<Type>, and ov::as_type_ptr<Type> for type-safe dynamic conversions via static_cast/static_ptr_cast without using C++ RTTI. Type must have a static type_info member and a virtual get_type_info() member that returns a reference to its type_info member.
