VkPresentStageFlagBitsEXT

Presenting an image to the user typically involves multiple stages. Bits which can be set to specify present stages are:

typedef enum VkPresentStageFlagBitsEXT {
    VK_PRESENT_STAGE_QUEUE_OPERATIONS_END_BIT_EXT = 0x00000001,
    VK_PRESENT_STAGE_REQUEST_DEQUEUED_BIT_EXT = 0x00000002,
    VK_PRESENT_STAGE_IMAGE_FIRST_PIXEL_OUT_BIT_EXT = 0x00000004,
    VK_PRESENT_STAGE_IMAGE_FIRST_PIXEL_VISIBLE_BIT_EXT = 0x00000008,
} VkPresentStageFlagBitsEXT;

pub struct PresentStageFlagBitsEXT(u32);
impl PresentStageFlagBitsEXT {
    pub const QUEUE_OPERATIONS_END: Self = 0x00000001;
    pub const REQUEST_DEQUEUED: Self = 0x00000002;
    pub const IMAGE_FIRST_PIXEL_OUT: Self = 0x00000004;
    pub const IMAGE_FIRST_PIXEL_VISIBLE: Self = 0x00000008;
}

• VK_PRESENT_STAGE_QUEUE_OPERATIONS_END_BIT_EXT marks the end of the set of queue operations enqueued by vkQueuePresentKHR on the provided VkQueue for a presentation request.
• VK_PRESENT_STAGE_REQUEST_DEQUEUED_BIT_EXT is the stage after which the presentation request has been dequeued from the swapchain’s internal presentation request queue, if any, as specified by the present mode associated with that request.
• VK_PRESENT_STAGE_IMAGE_FIRST_PIXEL_OUT_BIT_EXT is the stage after which data for the first pixel of the presentation request associated with the image has left the presentation engine for a display hardware.
• VK_PRESENT_STAGE_IMAGE_FIRST_PIXEL_VISIBLE_BIT_EXT is the stage after which a display hardware has made the first pixel visible for the presentation request associated with the image to be presented.
