VKSTRUCTURETYPE
VkStructureType, often seen as VK_STRUCTURE_TYPE in Vulkan, is an enumeration used to identify the concrete type of a Vulkan structure. Almost every Vulkan structure begins with two members: a VkStructureType named sType and a void pointer named pNext. The sType field must be set to the specific VK_STRUCTURE_TYPE_* value that corresponds to the structure being used.
The primary purpose of sType is to enable runtime validation and versioning. By inspecting sType, the Vulkan
Common usage involves setting sType to the appropriate value for the structure. For example, VkApplicationInfo uses
The VK_STRUCTURE_TYPE enumeration includes many values, with well-known entries such as VK_STRUCTURE_TYPE_APPLICATION_INFO, VK_STRUCTURE_TYPE_INSTANCE_CREATE_INFO, VK_STRUCTURE_TYPE_DEVICE_CREATE_INFO, VK_STRUCTURE_TYPE_MEMORY_ALLOCATE_INFO,
In summary, VkStructureType provides a standardized way to identify and validate Vulkan structures and to support
