> my assumption is that they specified `#[repr(packed(8))]` on some structs to use alignments and paddings of at most 8 bytes That would mean taking a reference of any field of that struct is undefined behavior, unless the compiler does some special magic for this specific case. > Using `[repr(align(8))]` on the field I don't think you can do that directly. You would need to use a newtype that specified the alignment, and use that type for the field.
