VkPhysicalDevicePipelineRobustnessPropertiesEXT

The VkPhysicalDevicePipelineRobustnessPropertiesEXT structure is defined as:

typedef struct VkPhysicalDevicePipelineRobustnessPropertiesEXT {
    VkStructureType sType;
    void* pNext;
    VkPipelineRobustnessBufferBehaviorEXT defaultRobustnessStorageBuffers;
    VkPipelineRobustnessBufferBehaviorEXT defaultRobustnessUniformBuffers;
    VkPipelineRobustnessBufferBehaviorEXT defaultRobustnessVertexInputs;
    VkPipelineRobustnessImageBehaviorEXT defaultRobustnessImages;
} VkPhysicalDevicePipelineRobustnessPropertiesEXT;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• defaultRobustnessStorageBuffers describes the behavior of out of bounds accesses made to storage buffers when no robustness features are enabled
• defaultRobustnessUniformBuffers describes the behavior of out of bounds accesses made to uniform buffers when no robustness features are enabled
• defaultRobustnessVertexInputs describes the behavior of out of bounds accesses made to vertex input attributes when no robustness features are enabled
• defaultRobustnessImages describes the behavior of out of bounds accesses made to images when no robustness features are enabled

Some implementations of Vulkan may be able to guarantee that certain types of accesses are always performed with robustness even when the Vulkan API’s robustness features are not explicitly enabled.

Even when an implementation reports that accesses to a given resource type are robust by default, it remains invalid to make an out of bounds access without requesting the appropriate robustness feature.

If the VkPhysicalDevicePipelineRobustnessPropertiesEXT structure is included in the pNext chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.
