VkDisplayEventTypeEXT

Possible values of VkDisplayEventInfoEXT::displayEvent, specifying when a fence will be signaled, are:

typedef enum VkDisplayEventTypeEXT {
    VK_DISPLAY_EVENT_TYPE_FIRST_PIXEL_OUT_EXT = 0,
} VkDisplayEventTypeEXT;

pub struct DisplayEventTypeEXT(u32);
impl DisplayEventTypeEXT {
    pub const FIRST_PIXEL_OUT: Self = 0;
}

• VK_DISPLAY_EVENT_TYPE_FIRST_PIXEL_OUT_EXT specifies that the fence is signaled when the first pixel of the next display refresh cycle leaves the display engine for the display.
