Struct riddle_platform_winit::PlatformSystem

pub struct PlatformSystem { /* fields omitted */ }

The winit platform system core state, along with PlatformMainThreadState.

Mostly used to lookup Window by WindowId, and subscribe to PlatformEvents.

Implementations

impl PlatformSystem

pub fn event_pub(&self) -> &EventPub<PlatformEvent>

Get the PlatformEvent publisher, so that other systems can consume events.

Example

let rdl =  RiddleLib::new()?;
let subscriber: EventSub<PlatformEvent> = EventSub::new();

// Attach subscriber to the platform event stream
rdl.state().platform().event_pub().attach(&subscriber);

pub fn lookup_window(&self, window_id: WindowId) -> Option<WindowHandle>

Get a WindowHandle associated with a WindowId, if one exists.

Example

let rdl =  RiddleLib::new()?;
let window = WindowBuilder::new().build(rdl.context())?;
let window_id = window.id();
assert!(WindowHandle::eq(&window,
       &rdl.state().platform().lookup_window(window_id).unwrap()));
