# Error code E0693

`align` representation hint was incorrectly declared.

Erroneous code examples:

    #![allow(unused)]
    fn main() {
    #[repr(align=8)] // error!
    struct Align8(i8);

    #[repr(align="8")] // error!
    struct Align8(i8);
    }

This is a syntax error at the level of attribute declarations. The proper syntax for `align` representation hint is the following:

    #![allow(unused)]
    fn main() {
    #[repr(align(8))] // ok!
    struct Align8(i8);
    }
