|
| Hook | Type | Rerender when? | Scope |
|
|
| ------------------------ | -------------------------- | ---------------------------- | ------------------- |
|
|
| [use_state] | `T` | got set | component instance |
|
|
| [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 |
|
|
| a static global variable | `T` | - | global, used by all |
