Trait Implementations

impl TransferDescriptorHandler for CommandRingTrbHandler

fn handle_transfer_descriptor( &self, descriptor: Vec<AddressedTrb>, complete_event: Event, ) -> Result<()>

Process descriptor asynchronously, write complete_event when done.

fn cancel(&self, _callback: RingBufferStopCallback)

Cancel transfer descriptors. This is called when stopping a ring buffer controller, due to receiving a Stop Endpoint command. There may be one or more transfers in-flight at the hardware level and the xHCI spec says we need to cancel or complete them before sending the completion event for the Stop Endpoint command. Use the callback to send the completion event once all the in-flight ones are cleared.
