pub struct WidgetId(_);
Expand description
The WidgetId
uniquely describes an instance of a widget.
Creating a new WidgetId
generates a new unique identifier which can
be safely copied and moved around; each copy refers to the same widget.
The intent is that you set up the identifiers once and re-use them,
rather than generating new ids on each iteration of the UI loop so that
the widget state is maintained correctly by the Ui.
