C Specification

The VkPipelineDiscardRectangleStateCreateInfoEXT structure is defined as:

// Provided by VK_EXT_discard_rectangles
typedef struct VkPipelineDiscardRectangleStateCreateInfoEXT {
    VkStructureType                                  sType;
    const void*                                      pNext;
    VkPipelineDiscardRectangleStateCreateFlagsEXT    flags;
    VkDiscardRectangleModeEXT                        discardRectangleMode;
    uint32_t                                         discardRectangleCount;
    const VkRect2D*                                  pDiscardRectangles;
} VkPipelineDiscardRectangleStateCreateInfoEXT;


  • sType is the type of this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • flags is reserved for future use.

  • discardRectangleMode is a VkDiscardRectangleModeEXT value determining whether the discard rectangle test is inclusive or exclusive.

  • discardRectangleCount is the number of discard rectangles to use.

  • pDiscardRectangles is a pointer to an array of VkRect2D structures defining discard rectangles.


If the VK_DYNAMIC_STATE_DISCARD_RECTANGLE_EXT dynamic state is enabled for a pipeline, the pDiscardRectangles member is ignored.

When this structure is included in the pNext chain of VkGraphicsPipelineCreateInfo, it defines parameters of the discard rectangle test. If this structure is not included in the pNext chain, it is equivalent to specifying this structure with a discardRectangleCount of 0.

Valid Usage
  • VUID-VkPipelineDiscardRectangleStateCreateInfoEXT-discardRectangleCount-00582
    discardRectangleCount must be less than or equal to VkPhysicalDeviceDiscardRectanglePropertiesEXT::maxDiscardRectangles

Valid Usage (Implicit)
  • VUID-VkPipelineDiscardRectangleStateCreateInfoEXT-sType-sType

  • VUID-VkPipelineDiscardRectangleStateCreateInfoEXT-flags-zerobitmask
    flags must be 0

  • VUID-VkPipelineDiscardRectangleStateCreateInfoEXT-discardRectangleMode-parameter
    discardRectangleMode must be a valid VkDiscardRectangleModeEXT value
