Struct devices::virtio::video::async_cmd_desc_map::AsyncCmdDescMap
source · pub struct AsyncCmdDescMap(BTreeMap<AsyncCmdTag, DescriptorChain>);Expand description
AsyncCmdDescMap is a BTreeMap which stores descriptor chains in which asynchronous responses will be written.

§0: BTreeMap<AsyncCmdTag, DescriptorChain>Implementations§
source§impl AsyncCmdDescMap
impl AsyncCmdDescMap
pub fn insert(&mut self, tag: AsyncCmdTag, descriptor_chain: DescriptorChain)
pub fn remove(&mut self, tag: &AsyncCmdTag) -> Option<DescriptorChain>
sourcepub fn create_cancellation_responses(
&self,
target_stream_id: &u32,
target_queue_type: Option<QueueType>,
processing_tag: Option<AsyncCmdTag>,
) -> Vec<AsyncCmdResponse>
pub fn create_cancellation_responses( &self, target_stream_id: &u32, target_queue_type: Option<QueueType>, processing_tag: Option<AsyncCmdTag>, ) -> Vec<AsyncCmdResponse>
Returns a list of AsyncCmdResponses to cancel pending commands that target
stream target_stream_id.
If target_queue_type is specified, then only create the requests for the specified queue.
Otherwise, create the requests for both input and output queue.
If processing_tag is specified, a cancellation request for that tag will
not be created.

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>

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)
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.
