fn init_root() -> Self::Root

Initializes the root widget.

fn init( url: Self::Init, root: &Self::Root, sender: ComponentSender<Self> ) -> ComponentParts<Self>

Creates the initial model and view, docking it into the component.

fn update( &mut self, input: Self::Input, sender: ComponentSender<Self>, root: &Self::Root )

Processes inputs received by the component.

fn update_cmd( &mut self, message: Self::CommandOutput, sender: ComponentSender<Self>, root: &Self::Root )

Defines how the component should respond to command updates.

fn builder() -> ComponentBuilder<Self>

Create a builder for this component.

fn update_cmd_with_view( &mut self, widgets: &mut Self::Widgets, message: Self::CommandOutput, sender: ComponentSender<Self>, root: &Self::Root )

Updates the model and view upon completion of a command.

fn update_view( &self, widgets: &mut Self::Widgets, sender: ComponentSender<Self> )

Updates the view after the model has been updated.

fn update_with_view( &mut self, widgets: &mut Self::Widgets, message: Self::Input, sender: ComponentSender<Self>, root: &Self::Root )

Updates the model and view when a new input is received.

fn shutdown( &mut self, widgets: &mut Self::Widgets, output: Sender<Self::Output> )

Last method called before a component is shut down.

fn id(&self) -> String

An identifier for the component used for debug logging.

impl Debug for WebImage

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<WebImage> for WebImage

fn eq(&self, other: &WebImage) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
