A surface trait that exposes the ability to present images on the associtated swap chain.

Associated Types

type SwapchainImage: Borrow<B::ImageView> + Debug + Send + Sync

An opaque type wrapping the swapchain image.

Required methods

unsafe fn configure_swapchain(
    &mut self,
    device: &B::Device,
    config: SwapchainConfig
) -> Result<(), CreationError>

Set up the swapchain associated with the surface to have the given format.

unsafe fn unconfigure_swapchain(&mut self, device: &B::Device)

Remove the associated swapchain from this surface.

This has to be done before the surface is dropped.

unsafe fn acquire_image(
    &mut self,
    timeout_ns: u64
) -> Result<(Self::SwapchainImage, Option<Suboptimal>), AcquireError>

Acquire a new swapchain image for rendering.

May fail according to one of the reasons indicated in AcquireError enum.

Synchronization

The acquired image is available to render. No synchronization is required.
