VkPresentTimingInfoEXT

The VkPresentTimingInfoEXT structure is defined as:

typedef struct VkPresentTimingInfoEXT {
    VkStructureType sType;
    const void* pNext;
    VkPresentTimingInfoFlagsEXT flags;
    uint64_t targetTime;
    uint64_t timeDomainId;
    VkPresentStageFlagsEXT presentStageQueries;
    VkPresentStageFlagsEXT targetTimeDomainPresentStage;
} VkPresentTimingInfoEXT;

pub struct PresentTimingInfoEXT {
    s_type: vk::StructureType,
    p_next: *const c_void,
    flags: vk::PresentTimingInfoFlagsEXT,
    target_time: u64,
    time_domain_id: u64, // Time domain to interpret the target present time and collect present stages timings with
    present_stage_queries: vk::PresentStageFlagsEXT, // Present stages to collect timing information for
    target_time_domain_present_stage: vk::PresentStageFlagsEXT, // Target stage-local time domain's stage
}

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• flags is a bitmask of VkPresentTimingInfoFlagBitsEXT specifying options for how to interpret the timing information.
• targetTime is zero or a value specifying the target present time or duration, in nanoseconds, of the presentation request.
• timeDomainId is the id of the time domain used to specify the absolute target present time and the timing results obtained in a subsequent vkGetPastPresentationTimingEXT call for the current presentation request.
• presentStageQueries is a valid VkPresentStageFlagsEXT value indicating which present stages the presentation engine will collect timing information for.
• targetTimeDomainPresentStage is a valid VkPresentStageFlagsEXT specifying a single present stage used to interpret targetTime.

If targetTime is not zero, the implementation attempts to align the VK_PRESENT_STAGE_IMAGE_FIRST_PIXEL_VISIBLE_BIT_EXT present stage of that presentation request with the time specified in targetTime according to the time domain used. If VK_PRESENT_TIMING_INFO_PRESENT_AT_NEAREST_REFRESH_CYCLE_BIT_EXT is not set in flags, it indicates that the application would strictly prefer the image to not be visible before targetTime has lapsed.

If targetTime is not zero and timeDomainId is associated with a VK_TIME_DOMAIN_PRESENT_STAGE_LOCAL_EXT time domain, targetTimeDomainPresentStage is used to specify which present stage’s time domain targetTime is specified for. Otherwise, targetTimeDomainPresentStage is ignored.
