Struct wayland_client::event_queue::QueueHandle

source ·
pub struct QueueHandle<State> {
    pub(crate) inner: Arc<Mutex<EventQueueInner<State>>>,
}
Expand description

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

Fields§

§inner: Arc<Mutex<EventQueueInner<State>>>

Implementations§

source§

impl<State: 'static> QueueHandle<State>

source

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.

source

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.

source§

impl<T> Downcast for T
where T: Any,

source§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
source§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.
source§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
source§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
source§

impl<T> DowncastSync for T
where T: Any + Send + Sync,

source§

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
source§

impl<T> From<T> for T

source§

fn from(t: T) -> T

Returns the argument unchanged.

source§

impl<T, U> Into<U> for T
where U: From<T>,

source§

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.
