* remove ToHtml trait * re-add display impls * make Vec::clone expilit * fix doc * fix conflicting impls Into<Html> and Display can't be implemented on the same type * update docs * blanket impl won't work here * bring back `Vec<VNode>: IntoPropValue<VNode>` * macro tests * Revert "fix conflicting impls" This reverts commit 52f3c1fa8174489ba9cc783d708a49cc7b9c90a4. These impls are fine now * make examples compile * .clone() should be before .into() * Rc VList * Make use of ImplicitClone and AttrValue in example (There is more work to do but it's complicated so I will do it in another PR) * Impl ImplicitClone on VChild --------- Co-authored-by: Cecile Tonglet <cecile.tonglet@cecton.com>
