Struct nobs_vulkanism::wnd::swapchain::Swapchain

pub struct Swapchain {
    pub extent: Extent2D,
    pub handle: SwapchainKHR,
    pub images: Vec<Image>,
    pub views: Vec<ImageView>,
    pub signals: Vec<Semaphore>,
    // some fields omitted
}

Wrapper around a vulkan swapchain

Additionally implements commands for blitting an image to the swapchain and presenting the swapchain image.

Fields

extent: Extent2D

handle: SwapchainKHR

images: Vec<Image>

views: Vec<ImageView>

signals: Vec<Semaphore>

Methods

impl Swapchain

pub fn build(
    inst: Instance,
    pdevice: PhysicalDevice,
    device: Device,
    surface: SurfaceKHR
) -> Builder

Return a swapchain builder

pub fn next_image(&mut self) -> NextImage

Aquire the next swapchain image

This function is usually called once every frame, before commands are submitted to draw to the swapchain image Returns a NextImage, with the index of the swapchain image and a semaphore that is signalled when the image is ready.

pub fn blit(&self, index: u32, src: Image) -> Blit

Returns a blit command

The command is configured to blit the specified src image to the swapchain image at position index.

pub fn present(&self, q: Queue, index: u32, wait_for: &[Semaphore])

Presents a swapchain image

Presents the swapchain image at position index after all semaphores in wait_for have been signalled. The queue needs to be a presentable queue.
