Struct RenderEntityMap 

pub struct RenderEntityMap {
    pub rect: HashMap<Entity, Entity>,
    pub text: HashMap<Entity, Entity>,
    pub shadow: HashMap<Entity, Vec<Entity>>,
    pub outline: HashMap<Entity, Entity>,
    pub border: HashMap<Entity, Entity>,
    pub image: HashMap<Entity, Entity>,
    pub svg: HashMap<Entity, Entity>,
    pub clip: HashMap<Entity, Entity>,
    pub scrollbar: HashMap<Entity, Entity>,
}

Persistent map from a main-world entity to its render-world entity for each Extracted* type. Upserting extracts read the prior map, update render entities in place, and write the new map back; legacy despawn-and-respawn extracts leave their slot untouched.

Fields

rect: HashMap<Entity, Entity>

main_entity -> render_entity for ExtractedRect.

text: HashMap<Entity, Entity>

main_entity -> render_entity for ExtractedText.

shadow: HashMap<Entity, Vec<Entity>>

main_entity -> Vec<render_entity> for ExtractedShadow; one main entity can carry multiple stacked shadows.

outline: HashMap<Entity, Entity>

main_entity -> render_entity for ExtractedOutline.

border: HashMap<Entity, Entity>

main_entity -> render_entity for ExtractedBorder.

image: HashMap<Entity, Entity>

main_entity -> render_entity for ExtractedImage.

svg: HashMap<Entity, Entity>

main_entity -> render_entity for lumen_assets::ExtractedSvg. Stores only Entity ids so the core crate avoids a vello dependency.

clip: HashMap<Entity, Entity>

main_entity -> render_entity for ExtractedClipBox; one entry per scrollable or overflow-hidden container.

scrollbar: HashMap<Entity, Entity>

main_entity -> render_entity for ExtractedScrollbar; one entry per scroll container with visible overlay bars.

Trait Implementations

impl Component for RenderEntityMap

where Self: Send + Sync + 'static,

const STORAGE_TYPE: StorageType = bevy_ecs::component::StorageType::SparseSet

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]

impl Debug for RenderEntityMap

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

Formats the value using the given formatter.

impl Default for RenderEntityMap

fn default() -> RenderEntityMap

Returns the “default value” for a type.

impl Resource for RenderEntityMap

where Self: Send + Sync + 'static,
