pub fn run_frame<F, E>(config: AppConfig, frame: F) -> Result<(), RunError>where
F: for<'frame> FnMut(&mut FrameContext<'frame>) -> Result<(), E> + 'static,
E: Error + 'static,Expand description
Runs an application with one fallible, exit-capable frame closure.
The closure value is retained by the runtime for the complete event-loop lifetime, so captured
state persists between frames and across GPU generation recovery. FrameContext exposes the
current UI, compiled add-ons, GPU generation, and FrameContext::request_exit. Returning an
error preserves its Error::source chain and attributes it to ApplicationStage::Frame.
Requesting exit is a normal control signal and returns Ok(()) after exactly-once shutdown.
Use run_ui when the callback only needs imgui::Ui. Use run when initialization,
event, GPU recovery, or shutdown hooks are required.
