This is a perfect job for Streams. It will produce an
Ada.Streams.Stream_Element_Array rather than a "byte_array", but
it's essentially the same thing. In some cases a size might not be
the same as 'size, because the compiler can use the base_type'size.
e.g.
type little_integers is new integer range 0 .. 3;
for little_integers'size use 2;
would have a 'size of 2, but Streams would likely use Integer'size
instead.
