fn with_default_mut( &mut self, f: &mut dyn FnMut(&mut dyn DynWithDefault, &mut (dyn Any + 'static)), )
Create a temporary default value of the current type and provide it in a
closure. The callback’s first argument is
self and the second argument
is the new temporary default value. The callback can then modify the
value as needed.Source§fn clear_and_inspect_old(

fn clear_and_inspect_old( &mut self, f: &mut dyn FnMut(&mut dyn DynWithDefault, &mut (dyn Any + 'static)), )
Set
self to a new default value and inspect the previous value as the
second argument to the callback.fn clear(&mut self)
