Struct Core 

pub struct Core<T>
where
    T: App,
{ /* private fields */ }

The eframe application wrapper that drives an App, bridging eframe’s update loop with runtime event dispatch, keyboard handling, and rendering.

Implementations

impl<T> Core<T>

where T: App,

pub fn try_new( cc: &CreationContext<'_>, runtime: Runtime, app_creator: AppCreator<T>, ) -> Result<Self>

Core initialization

impl<T> Core<T>

where T: App,

pub fn handle_events( &mut self, event: RuntimeEvent, ctx: &Context, _frame: &mut Frame, ) -> Result<()>

Processes a single runtime event, marking shutdown as pending on RuntimeEvent::Exit and forwarding the event to the application.

Trait Implementations

impl<T> App for Core<T>

where T: App,

fn ui(&mut self, ui: &mut Ui, frame: &mut Frame)

Called each time the UI needs repainting, which may be many times per second. Put your widgets into a SidePanel, TopPanel, CentralPanel, Window or Area.

fn on_exit(&mut self, _gl: Option<&Context>)

Called once on shutdown, after Self::save.

fn clear_color(&self, _visuals: &Visuals) -> [f32; 4]

Background color values for the app, e.g. what is sent to gl.clearColor.

fn logic(&mut self, ctx: &Context, frame: &mut Frame)

Called once before each call to Self::ui, and additionally also called when the UI is hidden, but egui::Context::request_repaint was called.

fn update(&mut self, ctx: &Context, frame: &mut Frame)

👎Deprecated:

Use Self::ui instead

Called each time the UI needs repainting, which may be many times per second.

fn save(&mut self, _storage: &mut dyn Storage)

Called on shutdown, and perhaps at regular intervals. Allows you to save state.

fn auto_save_interval(&self) -> Duration

Time between automatic calls to Self::save

fn persist_egui_memory(&self) -> bool

Controls whether or not the egui memory (window positions etc) will be persisted (only if the “persistence” feature is enabled).

fn raw_input_hook(&mut self, _ctx: &Context, _raw_input: &mut RawInput)

A hook for manipulating or filtering raw input before it is processed by Self::update.
