Struct AppTexture 

pub struct AppTexture { /* private fields */ }

An app-owned GPU texture handed to Aetna for compositing. Cheap Arc-backed clone; pass into crate::tree::surface to display.

Construct via the backend constructor — aetna_wgpu::app_texture or aetna_vulkano::app_texture. The wrapper is type-erased so the El tree and paint stream stay backend-neutral.

Implementations

impl AppTexture

pub fn from_backend(inner: Arc<dyn AppTextureBackend>) -> Self

Wrap a backend-supplied implementation. Constructors in aetna-wgpu / aetna-vulkano are the intended entry points.

pub fn id(&self) -> AppTextureId

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

pub fn format(&self) -> SurfaceFormat

pub fn backend(&self) -> &dyn AppTextureBackend

Borrow the backend impl as a trait object. Backends call this from their record path and downcast to their concrete type.

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

Human-readable concrete backend type for diagnostics.
