# Error code E0634

A type has conflicting `packed` representation hints.

Erroneous code examples:

    #![allow(unused)]
    fn main() {
    #[repr(packed, packed(2))] // error!
    struct Company(i32);

    #[repr(packed(2))] // error!
    #[repr(packed)]
    struct Company(i32);
    }

You cannot use conflicting `packed` 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)] // ok!
    struct Company(i32);
    }
