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 elink: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.
