A component has a view and can update itself.

The update function returns an effect which can contain follow ups and effects. Follow ups are executed on the next update loop of this component, while the effects are executed on the parent component that mounts it.

Required Methods

fn update(&mut self, msg: MSG) -> Effects<MSG, XMSG>

Update the model of this component and return follow up and/or effects that will be executed on the next update loop

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

the view of the component

Provided Methods

fn style(&self) -> String

optionally a Component can specify its own css style

fn get_component_id(&self) -> Option<&String>

Component can have component id to identify themselves

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
