error: unsupported representation for deriving FromBytes, AsBytes, or Unaligned on an enum

= help: valid reprs are `Rust` (default), `C`, `align`, `packed`, `transparent`, `simd`, `i8`, `u8`, `i16`, `u16`, `i32`, `u32`, `i64`, `u64`, `i128`, `u128`, `isize`, `usize`

= warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release!
