Struct yew::functional::HookUpdater

pub struct HookUpdater { /* fields omitted */ }

The HookUpdater provides a convenient interface for hooking into the lifecycle of the underlying Yew Component that backs the function component.

Two interfaces are provided - callback and post_render.

• callback allows the creation of regular yew callbacks on the host component.
• post_render allows the creation of events that happen after a render is complete.

See use_effect and use_context for more details on how to use the hook updater to provide function components the necessary callbacks to update the underlying state.

    F: FnOnce(&mut T) -> bool + 'static, 

Callback called after the render
