Struct QueueCompletion 

pub struct QueueCompletion { /* private fields */ }

The minimal state required to publish a completion to the used ring.

This is everything complete_descriptor needs — notably not the payload buffer descriptors, which are only used while the device is reading/writing guest memory. Devices that must buffer completions (e.g. in-order publication) can hold a QueueCompletion instead of a full VirtioQueueCallbackWork to avoid retaining the payload.
