Enum devices::virtio::video::device::VideoCmdResponseType

source · 
pub enum VideoCmdResponseType {
    Sync(CmdResponse),
    Async(AsyncCmdTag),
}
Expand description

A return value when a command from the guest is processed.

Variants§

§

Sync(CmdResponse)

The response for a synchronous command. This can be returned to the guest immediately via command virtqueue.

§

Async(AsyncCmdTag)

The tag for an asynchronous command that the back-end device will complete. Once the command is completed, its result will be sent with the same tag. This can be seen as a poor man’s future pattern.

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

§

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.
§

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.
§

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.
§

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.

§

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

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