error[E0277]: the trait bound `NotZerocopy: zerocopy::IntoBytes` is not satisfied

18 |     takes_into_bytes::<NotZerocopy>();
   |                        ^^^^^^^^^^^ the trait `zerocopy::IntoBytes` is not implemented for `NotZerocopy`
   |
   = note: Consider adding `#[derive(IntoBytes)]` to `NotZerocopy`
   = help: the following other types implement trait `zerocopy::IntoBytes`:
             ()
             AU16
             AtomicBool
             AtomicI16
             AtomicI32
             AtomicI64
             AtomicI8
             AtomicIsize
           and $N others
note: required by a bound in `takes_into_bytes`
