Struct wayland_client::QueueHandle
source · pub struct QueueHandle<State> { /* private fields */ }
Expand description
A handle representing an EventQueue
, used to assign objects upon creation.
Implementations§
source§impl<State: 'static> QueueHandle<State>
impl<State: 'static> QueueHandle<State>
sourcepub fn make_data<I: Proxy + 'static, U: Send + Sync + 'static>(
&self,
user_data: U,
) -> Arc<dyn ObjectData>where
State: Dispatch<I, U, State>,
pub fn make_data<I: Proxy + 'static, U: Send + Sync + 'static>(
&self,
user_data: U,
) -> Arc<dyn ObjectData>where
State: Dispatch<I, U, State>,
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
.
sourcepub fn freeze(&self) -> QueueFreezeGuard<'_, State>
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
QueueFreezeGuard
s associated with the queue are dropped.
