VkPipelineRobustnessCreateInfoEXT

The VkPipelineRobustnessCreateInfoEXT structure is defined as:

typedef struct VkPipelineRobustnessCreateInfoEXT {
    VkStructureType sType;
    const void* pNext;
    VkPipelineRobustnessBufferBehaviorEXT storageBuffers;
    VkPipelineRobustnessBufferBehaviorEXT uniformBuffers;
    VkPipelineRobustnessBufferBehaviorEXT vertexInputs;
    VkPipelineRobustnessImageBehaviorEXT images;
} VkPipelineRobustnessCreateInfoEXT;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• storageBuffers sets the behavior of out of bounds accesses made to resources bound as:
  • VK_DESCRIPTOR_TYPE_STORAGE_BUFFER
  • VK_DESCRIPTOR_TYPE_STORAGE_TEXEL_BUFFER
  • VK_DESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMIC
• uniformBuffers describes the behavior of out of bounds accesses made to resources bound as:
  • VK_DESCRIPTOR_TYPE_UNIFORM_TEXEL_BUFFER
  • VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER
  • VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC
  • VK_DESCRIPTOR_TYPE_INLINE_UNIFORM_BLOCK
• vertexInputs describes the behavior of out of bounds accesses made to vertex input attributes
• images describes the behavior of out of bounds accesses made to resources bound as:
  • VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE
  • VK_DESCRIPTOR_TYPE_STORAGE_IMAGE

Resources bound as VK_DESCRIPTOR_TYPE_MUTABLE_EXT will have the robustness behavior that covers its active descriptor type.

The scope of the effect of VkPipelineRobustnessCreateInfoEXT depends on which structure’s pNext chain it is included in.

• VkGraphicsPipelineCreateInfo, VkRayTracingPipelineCreateInfoKHR, VkComputePipelineCreateInfo:\
  The robustness behavior described by VkPipelineRobustnessCreateInfoEXT applies to all accesses through this pipeline
• VkPipelineShaderStageCreateInfo:\
  The robustness behavior described by VkPipelineRobustnessCreateInfoEXT applies to all accesses emanating from the shader code of this shader stage

If VkPipelineRobustnessCreateInfoEXT is specified for both a pipeline and a pipeline stage, the VkPipelineRobustnessCreateInfoEXT specified for the pipeline stage will take precedence.

When VkPipelineRobustnessCreateInfoEXT is specified for a pipeline, it only affects the subset of the pipeline that is specified by the create info, as opposed to subsets linked from pipeline libraries. For VkGraphicsPipelineCreateInfo, that subset is specified by VkGraphicsPipelineLibraryCreateInfoEXT::flags. For VkRayTracingPipelineCreateInfoKHR, that subset is specified by the specific stages in VkRayTracingPipelineCreateInfoKHR::pStages.
