Struct winit::platform_impl::platform::wayland::event_loop::state::WinitState

pub struct WinitState {
    pub event_sink: EventSink,

    pub window_map: HashMap<WindowId, WindowHandle>,
}

Wrapper to carry winit’s state.

Fields

event_sink: EventSink

A sink for window and device events that is being filled during dispatching event loop and forwarded downstream afterwards.

window_user_requests: HashMap<WindowId, WindowUserRequest>

Window updates comming from the user requests. Those are separatelly dispatched right after MainEventsCleared.

window_compositor_updates: HashMap<WindowId, WindowCompositorUpdate>

Window updates, which are coming from SCTK or the compositor, which require calling back to the winit’s downstream. They are handled right in the event loop, unlike the ones coming from buffers on the WindowHandle’s.

window_map: HashMap<WindowId, WindowHandle>

Window map containing all SCTK windows. Since those windows aren’t allowed to be sent to other threads, they live on the event loop’s thread and requests from winit’s windows are being forwarded to them either via WindowUpdate or buffer on the associated with it WindowHandle.
