use_state_eq	T: PartialEq	got set with diff. value	component instance
use_reducer	T: Reducible	got reduced	component instance
use_reducer_eq	T: Reducible + PartialEq	got reduced with diff. value	component instance
use_memo	Deps -> T	dependencies changed	component instance
use_callback	Deps -> Callback<E>	dependencies changed	component instance
use_mut_ref	T	-	component instance
