Required Methods§
sourcefn init(
init: Self::Init,
root: &Self::Root,
sender: ComponentSender<Self>
) -> ComponentParts<Self>
fn init( init: Self::Init, root: &Self::Root, sender: ComponentSender<Self> ) -> ComponentParts<Self>
Creates the initial model and view, docking it into the component.
Provided Methods§
sourcefn update(&mut self, message: Self::Input, sender: ComponentSender<Self>)
fn update(&mut self, message: Self::Input, sender: ComponentSender<Self>)
Processes inputs received by the component.
sourcefn update_cmd(
&mut self,
input: &Sender<Self::Input>,
output: Sender<Self::Output>
)
fn update_cmd( &mut self, input: &Sender<Self::Input>, output: Sender<Self::Output> )
Defines how the component should respond to command updates.
sourcefn update_view(
&self,
widgets: &mut Self::Widgets,
sender: ComponentSender<Self>
)
fn update_view( &self, widgets: &mut Self::Widgets, sender: ComponentSender<Self> )
Updates the view after the model has been updated.
