Struct HandleKinds 

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

Type-erased index over every kind registered via BrinkHandleAppExt::register_handle_kind for marker M. BTreeMap keyed by HandleKind::KIND for deterministic iteration.

Implementations

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

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

The kind names registered so far, in deterministic order.

pub fn is_empty(&self) -> bool

true when no HandleKind is registered for M — the whole registry-GC machinery is inert, so the -> DONE reachable-token sweep has provably nothing to collect and can be skipped (#1007).

Trait Implementations

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

fn default() -> Self

Returns the “default value” for a type.

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

where Self: Send + Sync + 'static,
