Struct DeviceGroup

Implementations

impl DeviceGroup

pub fn new(instance: &Instance, device: &Device) -> Self

Warning

Instance functions cannot be loaded from a Device and will always panic when called:

• Self::get_physical_device_present_rectangles()

Load this struct using an Instance instead via Self::new_from_instance() if the above Instance function is called. This will be solved in the next breaking ash release: https://github.com/ash-rs/ash/issues/727.

pub fn new_from_instance( entry: &Entry, instance: &Instance, device: Device, ) -> Self

Loads all functions on the Instance instead of Device. This incurs an extra dispatch table for Device functions but also allows the Instance function to be loaded instead of always panicking. See also Self::new() for more details.

It is okay to pass vk::Device::null() when this struct is only used to call the Instance function.

pub unsafe fn get_device_group_present_capabilities( &self, device_group_present_capabilities: &mut DeviceGroupPresentCapabilitiesKHR, ) -> VkResult<()>

Requires VK_KHR_surface to be enabled.

Also available as Swapchain::get_device_group_present_capabilities() since Vulkan 1.1.

pub unsafe fn get_device_group_surface_present_modes( &self, surface: SurfaceKHR, ) -> VkResult<DeviceGroupPresentModeFlagsKHR>

Requires VK_KHR_surface to be enabled.

Also available as Swapchain::get_device_group_surface_present_modes() since Vulkan 1.1.

pub unsafe fn get_physical_device_present_rectangles( &self, physical_device: PhysicalDevice, surface: SurfaceKHR, ) -> VkResult<Vec<Rect2D>>

Requires VK_KHR_surface to be enabled.

Also available as Swapchain::get_physical_device_present_rectangles() since Vulkan 1.1.

https://www.khronos.org/registry/vulkan/specs/1.3-extensions/man/html/vkGetPhysicalDevicePresentRectanglesKHR.html

Warning

Function will always panic unless this struct is loaded via Self::new_from_instance().

pub unsafe fn acquire_next_image2( &self, acquire_info: &AcquireNextImageInfoKHR, ) -> VkResult<(u32, bool)>

On success, returns the next image’s index and whether the swapchain is suboptimal for the surface.

Requires VK_KHR_swapchain to be enabled.

Also available as Swapchain::acquire_next_image2() since Vulkan 1.1.
