Expand description

Define the behavior to update the model of the main app.


impl AppUpdate for AppModel {
    fn update(&mut self, msg: AppMsg, _components: &(), _sender: Sender<AppMsg>) -> bool {
        match msg {
            AppMsg::Increment => {
                self.counter += 1;
            AppMsg::Decrement => {
                self.counter -= 1;

Required Methods

Updates the model. Typically a match statement is used to process the message.

Return true to continue running the application and return false to quit.

Components and sender don’t need to be used but help you sending messages to your components or queuing messages for self.
