class | VulkanContext
struct | VulkanDispatchData
class | VulkanMemoryAllocator
| Vulkan Memory Allocator class interface for managing large memory requests stored as contiguous blocks of memory, which are then sub-allocated into smaller regions of memory to avoid the excessive cost of vkAllocate and the limited number of available allocation calls through the API. More...
