pub type RootVisitorMut<'a, 'f> = dyn FnMut(EffectRootKind, &str, &str, &'a mut [QuestEffect]) + 'f;Expand description
The callback for_each_effect_root_mut hands each root to:
(kind, json_pointer_to_the_list, l10n_keybase, list). 'a ties the effects
to the campaign borrow, so a consumer may collect them; 'f is the callback’s
own borrow.
