Required methods

fn create(props: Self::Properties, link: ComponentLink<Self>) -> Self

Initialization routine which could use a context.

fn update(&mut self, msg: Self::Message) -> ShouldRender

Called everytime when a messages of Msg type received. It also takes a reference to a context.

Provided methods

fn change(&mut self, _: Self::Properties) -> ShouldRender

Called when the component's parent component re-renders and the component's place in the DOM tree remains unchanged. If the component's place in the DOM tree changes, calling this method is unnecessary as the component is recreated from scratch. It defaults to true if not implemented.

fn destroy(&mut self)

Called for finalization on the final point of the component's lifetime.
