Struct CapabilityRegistry 

pub struct CapabilityRegistry<M: Send + Sync + 'static = ()> { /* private fields */ }

App-level registry mapping capability names to ComponentIds, keyed by marker M (mirrors HandleKinds<M>). Populated via BrinkCapabilityAppExt::register_capability. BTreeMap for deterministic iteration (CLAUDE.md determinism rule).

Implementations

impl<M: Send + Sync + 'static> CapabilityRegistry<M>

pub fn component_id(&self, name: &str) -> Option<ComponentId>

Resolve a registered capability name to its ComponentId. None means no register_capability call has claimed this name yet.

pub fn type_id(&self, name: &str) -> Option<TypeId>

Resolve a registered capability name to its concrete component’s TypeId — the key BH-4’s Detect phase (crate::sleep) uses to look the capability’s per-frame change verdict up in CapabilityChanges (§12.5). None means no register_capability call has claimed this name, so the capability is untracked: the wake layer must conservatively must-poll it (it cannot prove the component is unchanged, and a missed wake is the engine-race bug class).

pub fn names(&self) -> impl Iterator<Item = &'static str> + '_

The capability names registered so far, in deterministic order.

Trait Implementations

impl<M: Send + Sync + 'static> Component for CapabilityRegistry<M>

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<M: Send + Sync + 'static> Default for CapabilityRegistry<M>

fn default() -> Self

Returns the “default value” for a type.

impl<M: Send + Sync + 'static> Resource for CapabilityRegistry<M>
