Struct ExtractedImageBlob 

pub struct ExtractedImageBlob(pub Blob<u8>);

Render-world sidecar carrying a pre-built peniko::Blob for an extracted image. Queried alongside ExtractedImage by the renderer so the Blob reaches the painter unchanged, preserving its upload-cache identity.

Node IR splice (W2.1 follow-up)

The retained Node IR’s Node::Image { blob: Option<Arc<dyn Any + Send + Sync>> } already accepts this payload as an opaque Arc<dyn Any> so the walker downcasts back to ExtractedImageBlob and paints it. On the on-screen winit path the splice is handled today by render_frame reading both ExtractedImage and ExtractedImageBlob in lockstep and emitting the image draw alongside the retained-tree walk; the same splice is the reason the offscreen retained-tree path doesn’t yet light up images. The audit-follow-up that finishes the migration must update lumen_core::node_ir::transform_extracted_to_nodes to query ExtractedImageBlob and set Node::Image.blob = Some(Arc::new(blob.clone())) directly - which requires a core-touching PR that this crate is not allowed to perform alone.

Trait Implementations

impl Clone for ExtractedImageBlob

fn clone(&self) -> ExtractedImageBlob

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Component for ExtractedImageBlob

where Self: Send + Sync + 'static,

const STORAGE_TYPE: StorageType = bevy_ecs::component::StorageType::Table

A constant indicating the storage type used for this component.

type Mutability = Mutable

A marker type to assist Bevy with determining if this component is mutable, or immutable. Mutable components will have [Component<Mutability = Mutable>], while immutable components will instead have [Component<Mutability = Immutable>].

fn register_required_components( _requiree: ComponentId, required_components: &mut RequiredComponentsRegistrator<'_, '_>, )

Registers required components.

fn clone_behavior() -> ComponentCloneBehavior

Called when registering this component, allowing to override clone function (or disable cloning altogether) for this component.

fn relationship_accessor() -> Option<ComponentRelationshipAccessor<Self>>

Returns [ComponentRelationshipAccessor] required for working with relationships in dynamic contexts.

fn on_add() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_add [ComponentHook] for this [Component] if one is defined.

fn on_insert() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_insert [ComponentHook] for this [Component] if one is defined.

fn on_discard() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_discard [ComponentHook] for this [Component] if one is defined.

fn on_remove() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_remove [ComponentHook] for this [Component] if one is defined.

fn on_despawn() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_despawn [ComponentHook] for this [Component] if one is defined.

fn map_entities<E>(_this: &mut Self, _mapper: &mut E)

where E: EntityMapper,

Maps the entities on this component using the given [EntityMapper]. This is used to remap entities in contexts like scenes and entity cloning. When deriving [Component], this is populated by annotating fields containing entities with #[entities]
