Struct QueueHandle

pub struct QueueHandle<State> { /* private fields */ }

Available on crate feature wayland and Linux only.

A handle representing an EventQueue, used to assign objects upon creation.

Implementations

impl<State> QueueHandle<State>

where State: 'static,

pub fn make_data<I, U>(&self, user_data: U) -> Arc<dyn ObjectData>

where I: Proxy + 'static, U: Send + Sync + 'static, State: Dispatch<I, U>,

Create an object data associated with this event queue

This creates an implementation of ObjectData fitting for direct use with wayland-backend APIs that forwards all events to the event queue associated with this token, integrating the object into the Dispatch-based logic of wayland-client.

pub fn freeze(&self) -> QueueFreezeGuard<'_, State>

Temporarily block processing on this queue.

This will cause the associated queue to block (or return NotReady to poll) until all QueueFreezeGuards associated with the queue are dropped.
