32. Debugging
To aid developers in tracking down errors in the application’s use of Vulkan, particularly in combination with an external debugger or profiler, debugging extensions may be available.
The VkObjectType enumeration defines values, each of which corresponds to a specific Vulkan handle type. These values can be used to associate debug information with a particular type of object through one or more extensions.
typedef enum VkObjectType {
VK_OBJECT_TYPE_UNKNOWN = 0,
VK_OBJECT_TYPE_INSTANCE = 1,
VK_OBJECT_TYPE_PHYSICAL_DEVICE = 2,
