A TYPE with this trait has a trivial default constructor. Objects of a type with this trait can be default-initialized by simply writing zeros into the memory footprint of the object. Although it is possible for such a type not to be bitwise copyable, undefined behavior may result if this trait is assigned to such a type. (See the description of TypeTraitBitwiseCopyable.)
