Describe the bug

I am using sol! macro to generate enum to use it for eip712 signing but when see the hash struct it is wrong. After investigate, I found that the as_u8 is wrong as i tested on rust playground

#[derive(Clone, Copy)]
#[repr(u8)]
enum Color {
    Red = 0,
    Green = 1,
    Blue = 2,
}

impl Color {
    fn as_u8(&self) -> &u8 {
        unsafe { &*::core::ptr::addr_of!(self).cast::<u8>() }
    }
}

fn main() {
    let color = Color::Red;
    let u8_value = color.as_u8();
    println!("The u8 value of the color is: {}", u8_value);
}

For this code it will print something like "The u8 value of the color is: 159"
