Return, by value, a datum referring to the copy of the specified `value` of the specified `size`, using the specified `allocator` to supply memory (if needed). The behavior is undefined unless `size <= UINT_MAX`. Note that the copy of the binary data is owned and will be freed if `Datum::destroy` is called on the returned object.
