VkPresentTimingSurfaceCapabilitiesEXT

The VkPresentTimingSurfaceCapabilitiesEXT structure is defined as:

typedef struct VkPresentTimingSurfaceCapabilitiesEXT {
    VkStructureType sType;
    void* pNext;
    VkBool32 presentTimingSupported;
    VkBool32 presentAtAbsoluteTimeSupported;
    VkBool32 presentAtRelativeTimeSupported;
    VkPresentStageFlagsEXT presentStageQueries;
} VkPresentTimingSurfaceCapabilitiesEXT;

pub struct PresentTimingSurfaceCapabilitiesEXT {
    s_type: vk::StructureType,
    p_next: *mut c_void,
    present_timing_supported: vk::Bool32, // presentation timings of the surface can be queried using vkGetPastPresentationTimingEXT
    present_at_absolute_time_supported: vk::Bool32, // surface can be presented using absolute times
    present_at_relative_time_supported: vk::Bool32, // surface can be presented using relative times
    present_stage_queries: vk::PresentStageFlagsEXT, // present stages that can be queried
}

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• presentTimingSupported indicates whether querying presentation timestamps is supported for a swapchain created from VkPhysicalDeviceSurfaceInfo2KHR::surface.
• presentAtAbsoluteTimeSupported indicates whether a swapchain created from VkPhysicalDeviceSurfaceInfo2KHR::surface supports presenting images with absolute times.
• presentAtRelativeTimeSupported indicates whether a swapchain created from VkPhysicalDeviceSurfaceInfo2KHR::surface supports presenting images with relative times.
• presentStageQueries is a bitmask of VkPresentStageFlagBitsEXT indicating which present stages a swapchain created from VkPhysicalDeviceSurfaceInfo2KHR::surface is able to provide timing information for.

If presentTimingSupported is VK_TRUE, the implementation must also advertise support for at least the VK_PRESENT_STAGE_QUEUE_OPERATIONS_END_BIT_EXT present stage in pname presentStageQueries.
