pub trait HasId {
// Required method
fn has_id(self) -> Id;
}Expand description
Types supporting conversion to Id
A method taking an id: impl HasId parameter supports an Id,
a reference to an Id (which is thus cloned),
or a (mutable) reference to a widget.
Note: in some cases attempting to pass a widget reference does not pass
borrow checks. In this case pass widget.id() explicitly.
