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.

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 style(&self) -> String

optionally an Application can specify its own css style

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

fn observed_attributes() -> Vec<&'static str>

returns the attributes that is observed by this component

fn attributes_changed(&mut self, _attributes_values: BTreeMap<String, String>)

This will be invoked when a component is used as a custom element and the attributes of the custom-element has been modified

fn attributes_for_mount(&self) -> BTreeMap<String, String>

This will be invoked when a component needs to set the attributes for the mounted element of this component
