error: borrowed data escapes outside of associated function

[Magicloud]

Consider this code piece:

struct Page {
  state: Arc<Option<HashSet<String>>>
}
impl Component for Page {
  fn view(&self, ctx: &Context<Self>) -> Html {
    match &*self.state {
      Some(s) => {
        s.iter().something_more()
      }
    }
  }
}

I got error on s.iter() line as the subject. It says self lifetime must outlive "static". How could I avoid the clone of the huge HashSet?

I see. The problem is way down on a callback.
