will this need to be generated in sol! for all structs?

Can be done with a blanket impl:

impl<T: SolStruct> EventTopic for T
where
    T::Tuple: EventTopic,
{
    fn topic_preimage_length(rust: &T) -> usize {
        let tuple = rust.to_rust();
        T::Tuple::topic_preimage_length(&tuple)
    }
}

But we're cloning the data to get the inner tuple, so this is not ideal

I'm gonna think about this a bit more. what do you think of this:

trait SolType {

    type BorrowAbstraction: From<Self::RustType>;

    fn encode<T: Into<Self::BorrowAbstraction>>(t: T)

}

pub enum TupleBorrowAbstraction<T, U> {
    Owned((T,U)),
    Borrowed(&(T, U)),
    MembersBorrowed((&T, &U))
}

// From impls here
