Struct LifecycleConfig 

pub struct LifecycleConfig {
    pub on_close: Option<Box<dyn FnMut() + Send>>,
    pub on_resize: Option<Box<dyn FnMut(f32, f32) + Send>>,
    pub on_focus: Option<Box<dyn FnMut(bool) + Send>>,
}

Lifecycle callbacks passed to a BackendRunner at startup.

Backends call these closures when the corresponding window event fires. Closures that are None are silently skipped.

Fields

on_close: Option<Box<dyn FnMut() + Send>>

Called when the window close button is pressed or the process is asked to quit.

on_resize: Option<Box<dyn FnMut(f32, f32) + Send>>

Called when the window is resized; arguments are the new (width, height) in logical pixels.

on_focus: Option<Box<dyn FnMut(bool) + Send>>

Called when the window gains (true) or loses (false) focus.
