Struct ArraySignals 

pub struct ArraySignals(pub HashMap<String, Vec<ArrayItem>>, _);

Reactive array store paired with Signals; ordered vectors of ArrayItem keyed by name. Written through ScriptCommand::SetArray; the reconciler system spawns/despawns markup children to match the stored vector.

Wave-D follow-up: a future migration may collapse this into PropertyValue::Custom(Arc<ArrayItems>) so the typed property store becomes the single source of truth - left as a separate resource for now since the record-shaped data model doesn’t map cleanly onto the scalar typed cells.

The second field records the arrays whose contents changed this tick, the array counterpart of the PropertyStore dirty queue: a derived signal that depends on an array reads it to know when to recompute. It is emptied at the end of every tick by clear_array_signal_changes.

Implementations

impl ArraySignals

pub fn set(&mut self, name: impl Into<String>, items: Vec<ArrayItem>)

Replaces the contents of the named array with items. A write that changes the contents records the name in Self::changed.

pub fn changed(&self) -> impl Iterator<Item = &str>

Names of the arrays whose contents changed this tick.

pub fn get(&self, name: &str) -> Option<&[ArrayItem]>

Returns the named array as a slice, or None when absent.

pub fn touch(&mut self, name: &str)

No-op placeholder retained for forward-compatibility with an incremental-diff reconciler.

Trait Implementations

impl Clone for ArraySignals

fn clone(&self) -> ArraySignals

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Component for ArraySignals

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 ArraySignals

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

Formats the value using the given formatter.

impl Default for ArraySignals

fn default() -> ArraySignals

Returns the “default value” for a type.

impl Resource for ArraySignals

where Self: Send + Sync + 'static,
