Struct AshAppTexture 

pub struct AshAppTexture {
    pub image: Image,
    pub view: ImageView,
    pub image_layout: ImageLayout,
    /* private fields */
}

Host-owned ash texture that Damascene can sample during paint.

The image must be a single-sampled 2D image created with vk::ImageUsageFlags::SAMPLED, and the host must keep both the image and view alive while this wrapper may be painted. Before Damascene draw commands execute, the host must transition the image to the same readable layout recorded in this wrapper.

Fields

image: Image

view: ImageView

image_layout: ImageLayout

Trait Implementations

impl AppTextureBackend for AshAppTexture

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 Clone for AshAppTexture

fn clone(&self) -> AshAppTexture

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for AshAppTexture

impl Debug for AshAppTexture

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

Formats the value using the given formatter.
