Function yew::functional::use_hook

pub fn use_hook<InternalHook: 'static, Output, Tear: FnOnce(&mut InternalHook) + 'static>(
    initializer: impl FnOnce() -> InternalHook, 
    runner: impl FnOnce(&mut InternalHook, HookUpdater) -> Output, 
    destructor: Tear
) -> Output

Low level building block of creating hooks.

It is used to created the pre-defined primitive hooks. Generally, it isn’t needed to create hooks and should be avoided as most custom hooks can be created by combining other hooks as described in Yew Docs.

The initializer callback is called once to create the initial state of the hook. runner callback handles the logic of the hook. It is called when the hook function is called. destructor, as the name implies, is called to cleanup the leftovers of the hook.

See the pre-defined hooks for examples of how to use this function.
