Required Methods

fn render(
    &self,
    instance: &Instance,
    props: &Props,
    children: &Children
) -> View

Provided Methods

fn name(&self) -> &'static str

fn initial_state(&self, _props: &Props) -> Props

return the inital state of the component

fn context(&self, _props: &Props) -> Props

return the inital context of the component, gets passed to children via inherit_context

fn inherit_context(&self, context: Props, _parent_context: &Props) -> Props

filter the passed context of the component

fn will_mount(&self, _instance: &Instance)

called before mount

fn will_unmount(&self, _instance: &Instance)

called before unmount

fn will_update(&self, _instance: &Instance)

called before update

fn receive_props(
    &self,
    _instance: &Instance,
    _next_state: &Props,
    _next_props: &Props,
    _next_children: &Children
)

called when component receives new state, props, or children

fn should_update(
    &self,
    _prev_state: &Props,
    _prev_props: &Props,
    _prev_children: &Children,
    _next_state: &Props,
    _next_props: &Props,
    _next_children: &Children
) -> bool

if component needs update return true, defaults to true
