Struct WgpuAppTexture 

pub struct WgpuAppTexture {
    pub texture: Arc<Texture>,
    pub view: Arc<TextureView>,
    /* private fields */
}

Concrete wgpu-side AppTextureBackend. Holds the texture + view + a cached id so the runtime can downcast and pull what it needs without re-creating views per frame.

Fields

texture: Arc<Texture>

The app-owned texture. Held as Arc so AppTexture can be cheaply cloned into the El tree without releasing the GPU resource.

view: Arc<TextureView>

Default 2D view over the full texture, created once at construction so the per-frame record path doesn’t allocate.

Trait Implementations

impl AppTextureBackend for WgpuAppTexture

fn id(&self) -> AppTextureId

Stable identity allocated by the constructor — must round-trip the same value on every call for the lifetime of self.

fn size_px(&self) -> (u32, u32)

Pixel size of the underlying texture. The backend uses this for sanity checks; the widget rect comes from layout, not from here.

fn format(&self) -> SurfaceFormat

Pixel format of the underlying texture. Used by the backend to pick a sampler / shader path.

fn as_any(&self) -> &dyn Any

Downcast hatch for the backend’s record path. Each backend asserts the trait object is its own concrete type; mixing backends in one runtime is unsupported.

fn backend_name(&self) -> &'static str

Human-readable concrete backend type for diagnostics.

impl Debug for WgpuAppTexture

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

Formats the value using the given formatter.
