Struct SurfaceState 

pub struct SurfaceState {
    pub config: SurfaceConfiguration,
    pub depth: DepthTexture,
    /* private fields */
}

Swapchain surface and configuration for the active window.

Fields

config: SurfaceConfiguration

Current surface configuration (dimensions, format, present mode).

depth: DepthTexture

Depth buffer recreated on resize/reconfigure.

Implementations

impl SurfaceState

pub fn new( gpu: &GpuDevice, window: &Arc<Window>, width: u32, height: u32, ) -> Result<Self, WgpuBackendError>

Creates and configures the swapchain surface for the given window.

Errors

Returns WgpuBackendError::CreateSurface if surface creation fails.

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

Resizes the swapchain and recreates the depth buffer.

No-op if either dimension is zero.

pub fn reconfigure(&mut self, gpu: &GpuDevice)

Reconfigures the swapchain with the current config and recreates the depth buffer.

Called internally when the surface is lost or outdated.

pub fn acquire_frame( &mut self, gpu: &GpuDevice, ) -> Result<SurfaceTexture, WgpuBackendError>

Acquires the next swapchain texture, reconfiguring once on loss or staleness.

Errors

Returns WgpuBackendError::Surface if acquisition fails after one reconfigure attempt.

pub fn format(&self) -> TextureFormat

Returns the swapchain pixel format.
