An Application is the root component of your program. Everything that happens in your application is done here.

Required Methods

fn update(&mut self, _msg: MSG) -> Cmd<Self, MSG>where Self: Sized + 'static,

Update the component with a message. The update function returns a Cmd, which can be executed by the runtime.

Called each time an action is triggered from the view

fn view(&self) -> Node<MSG>

Returns a node on how the component is presented.

fn style(&self) -> String

optionally an Application can specify its own css style

Provided Methods

fn init(&mut self) -> Cmd<Self, MSG>where Self: Sized + 'static,

The application can implement this method where it can modify its initial state. This method is called right after the program is mounted into the DOM.

fn measurements(&self, measurements: Measurements) -> Cmd<Self, MSG>where Self: Sized + 'static,

This is called after dispatching and updating the dom for the component This is for diagnostic and performance measurement purposes.

Warning: DO NOT use for anything else other than the intended purpose

Implementors

impl<COMP, MSG> Application<MSG> for COMPwhere COMP: Component<MSG, ()> + 'static + CustomElement<MSG>, MSG: 'static,

Auto implementation of Application trait for Component that has no external MSG but only if that Component is intended to be a CustomElement
