        "Select your favorite fruit...",
        state.favorite.as_ref(),
        Message::FruitSelected
    )
    .into()
}

fn update(state: &mut State, message: Message) {
    match message {

            state.favorite = Some(fruit);
        }
    }

impl std::fmt::Display for Fruit {
    fn fmt(&self, f: &mut std::fmt::Formatter<'_>) -> std::fmt::Result {
