Trait Implementations

impl Component for ObservedBy

const STORAGE_TYPE: StorageType = 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 on_remove() -> Option<ComponentHook>

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

fn clone_behavior() -> ComponentCloneBehavior

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

fn register_component_hooks(hooks: &mut ComponentHooks)

👎Deprecated since 0.16.0: Use the individual hook methods instead (e.g., Component::on_add, etc.)

Called when registering this component, allowing mutable access to its ComponentHooks.

fn on_add() -> Option<ComponentHook>

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

fn on_insert() -> Option<ComponentHook>

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

fn on_replace() -> Option<ComponentHook>

Gets the on_replace ComponentHook for this Component if one is defined.

fn on_despawn() -> Option<ComponentHook>

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

fn register_required_components( _component_id: ComponentId, _components: &mut ComponentsRegistrator<'_>, _required_components: &mut RequiredComponents, _inheritance_depth: u16, _recursion_check_stack: &mut Vec<ComponentId>, )

Registers required components.

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

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 Default for ObservedBy

fn default() -> ObservedBy

Returns the “default value” for a type.
