error[E0793]: reference to packed field is unaligned

LL | let _ = &good.data;

= note: packed structs are only aligned by one byte, and many modern architectures penalize unaligned field accesses

= note: creating a misaligned reference is undefined behavior (even if that reference is never dereferenced)

= help: copy the field contents to a local variable, or replace the reference with a raw pointer and use `read_unaligned`/`write_unaligned` (loads and stores via `*p` must be properly aligned even when using raw pointers)
