The class 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
.
Notes
erased_type
is removed in LFTS v3 because std::pmr::polymorphic_allocator<> is preferable for type erasure.
