# 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);
    }
