# `repr_align_enum`

The tracking issue for this feature is: #57996

The `repr_align_enum` feature allows using the `#[repr(align(x))]` attribute on enums, similarly to structs.

# Examples

    #![feature(repr_align_enum)]

    #[repr(align(8))]
    enum Aligned {
        Foo,
        Bar { value: u32 },
    }

    fn main() {
        assert_eq!(std::mem::align_of::<Aligned>(), 8);
    }

This is equivalent to using an aligned wrapper struct everywhere:

    #[repr(align(8))]
    struct Aligned(Unaligned);

    enum Unaligned {
        Foo,
        Bar { value: u32 },
    }

    fn main() {
        assert_eq!(std::mem::align_of::<Aligned>(), 8);
    }
