Defined in header <experimental/utility>
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.
