struct erased_type{}; | (library fundamentals TS) (removed in library fundamentals TS v3) | |
The classerased_type is an empty struct that serves as a placeholder for a type in situations where the actual type is determined at runtime. For example, in classes that usetype-erased allocators, the nested typedefallocator_type is an alias forerased_type.
erased_type is removed in LFTS v3 becausestd::pmr::polymorphic_allocator<> is preferable for type erasure.
