impeller::QueueVK Class Reference

A thread safe object that can be used to access device queues. If multiple objects are created with the same underlying queue, then the external synchronization guarantees of Vulkan queues cannot be met. So care must be taken the same device queue doesn't form the basis of multiple QueueVKs. More...

Detailed Description

A thread safe object that can be used to access device queues. If multiple objects are created with the same underlying queue, then the external synchronization guarantees of Vulkan queues cannot be met. So care must be taken the same device queue doesn't form the basis of multiple QueueVKs.
