   |                                         ^^^^^^^^^^^^^^^^^^^ the trait `zerocopy::FromBytes` is not implemented for `NotZerocopy`

   = note: Consider adding `#[derive(FromBytes)]` to `NotZerocopy`
   = help: the following other types implement trait `zerocopy::FromBytes`:
             ()
             AU16
             AtomicI16
             AtomicI32

             AtomicI8
             AtomicIsize
             AtomicU16
           and $N others
