Struct demo_vk::graphics::vulkan::Swapchain

pub struct Swapchain { /* private fields */ }

The Vulkan swapchain and associated resources.

Implementations

impl Swapchain

pub fn new( cxt: Arc<VulkanContext>, framebuffer_size: (u32, u32), previous_swapchain: Option<SwapchainKHR>, ) -> Result<Self>

Creates a new Vulkan swapchain.

pub fn raw(&self) -> SwapchainKHR

Returns the non-owning Vulkan swapchain handle.

pub fn extent(&self) -> Extent2D

Returns the Swapchain’s current extent.

pub fn scissor(&self) -> Rect2D

Returns a scissor rect for the full swapchain extent.

pub fn viewport(&self) -> Viewport

pub fn format(&self) -> Format

Returns the Swapchain’s image format.

pub fn images(&self) -> &[Image]

Returns the Swapchain’s image handles.

pub fn image_views(&self) -> &[ImageView]

Returns the Swapchain’s image views.

Views are paired 1-1 with images of the same index.

pub fn acquire_image( &self, image_ready_semaphore: Semaphore, ) -> Result<AcquireImageStatus>

Acquires the index for the next swapchain image.

• image_ready_semaphore - A Vulkan semaphore to signal when the swapchain image is ready. This can be vk::Semaphore::null() if not required.

pub fn present_image( &self, wait_semaphore: Semaphore, image_index: u32, ) -> Result<PresentImageStatus>

Presents the swapchain image.

• wait_semaphore - Image presentation waits for the semaphore to be signalled.
• image_index - The index of the swapchain image being presented. This must come from a prior call to Self::acquire_image.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
