How to serialize / deserialize Nonce

[Antosser]

How can I define the Nonce type? This fails:

    struct Ser {
        nonce: Nonce<U12>,
    }

not found in this scope

Converting to a slice also doesn't seem to work, since it's unsized

    let nonce = aes_gcm::Aes256Gcm::generate_nonce(&mut rng).as_slice(); // &[u8]

How do I serialize a nonce?

Reading over it again, it seems I've not been as clear as I thought. I'll reopen a new issue right away
