Enum RenderTarget 

pub enum RenderTarget {
    Swapchain(SurfaceState),
}

Where a drawn frame lands.

A swapchain is a compositor’s: it hands out a texture, takes it back, and shows it. A texture is the caller’s, and nobody shows it — which is the only difference, and the reason a frame can be inspected without a compositor at all. Everything upstream of here draws the same commands either way.

Variants

Swapchain(SurfaceState)

The compositor’s swapchain. Acquired per frame, presented after.

Implementations

impl RenderTarget

pub fn width(&self) -> u32

pub fn height(&self) -> u32

pub fn resize(&mut self, width: u32, height: u32)

A swapchain is reconfigured; a texture is replaced.

Not a no-op for the texture, however tempting: resolve_geometry asks whether the target matches the frame and calls this when it does not, so a target that quietly declined would report a resize every frame for ever, repainting the whole tree each time and defeating the incremental paint the rest of the pipeline is built around.

pub fn device(&self) -> &Arc<Device>

pub fn queue(&self) -> &Arc<Queue>

pub fn format(&self) -> TextureFormat
