VkPhysicalDevicePresentTimingFeaturesEXT

The VkPhysicalDevicePresentTimingFeaturesEXT structure is defined as:

typedef struct VkPhysicalDevicePresentTimingFeaturesEXT {
    VkStructureType sType;
    void* pNext;
    VkBool32 presentTiming;
    VkBool32 presentAtAbsoluteTime;
    VkBool32 presentAtRelativeTime;
} VkPhysicalDevicePresentTimingFeaturesEXT;

pub struct PhysicalDevicePresentTimingFeaturesEXT {
    s_type: vk::StructureType,
    p_next: *mut c_void,
    present_timing: vk::Bool32, // vkGetPastPresentationTimingEXT is supported
    present_at_absolute_time: vk::Bool32, // Absolute time can be used to specify present time
    present_at_relative_time: vk::Bool32, // Relative time can be used to specify present duration
}

This structure describes the following feature:

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• FEATURES PRESENTTIMING
  presentTiming indicates that the implementation supports vkGetPastPresentationTimingEXT.
• FEATURES PRESENTATABSOLUTETIME
  presentAtAbsoluteTime indicates that the implementation supports specifying absolute target present times.
• FEATURES PRESENTATRELATIVETIME
  presentAtRelativeTime indicates that the implementation supports specifying relative target present times.

If the VkPhysicalDevicePresentTimingFeaturesEXT structure is included in the pNext chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a VkDevice with any features described by VkPhysicalDevicePresentTimingFeaturesEXT, it must add an instance of the structure, with the desired feature members set to VK_TRUE, to the pNext chain of VkDeviceCreateInfo when creating the VkDevice.
