struct erased_type { }; |  | (library fundamentals TS)

The struct `erased_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 use type-erased allocators, the nested typedef `allocator_type` is an alias for `erased_type`.
