Error code E0587
A type has both packed
and align
representation hints.
Erroneous code example:
#![allow(unused)] fn main() { #[repr(packed, align(8))] // error! struct Umbrella(i32); }
You cannot use packed
and align
hints on a same type. If you want to pack a
type to a given size, you should provide a size to packed:
#![allow(unused)] fn main() { #[repr(packed(8))] // ok! struct Umbrella(i32); }
