Struct bevy_hierarchy::Parent

pub struct Parent(_);

Holds a reference to the parent entity of this entity. This component should only be present on entities that actually have a parent entity.

See HierarchyQueryExt for hierarchy related methods on Query.

Implementations

impl Parent

pub fn get(&self) -> Entity

Gets the Entity ID of the parent.

Methods from Deref<Target = Entity>

pub const PLACEHOLDER: Entity = Self::from_raw(u32::MAX)

Trait Implementations

impl Component for Parentwhere Self: Send + Sync + 'static,

type Storage = TableStorage

impl Debug for Parent

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

Formats the value using the given formatter.

impl Deref for Parent

type Target = Entity

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl FromWorld for Parent

fn from_world(_world: &mut World) -> Self

Creates Self using data from the given World

impl GetTypeRegistration for Parentwhere Entity: Reflect,

fn get_type_registration() -> TypeRegistration

impl MapEntities for Parent

fn map_entities( &mut self, entity_map: &EntityMap ) -> Result<(), MapEntitiesError>

Updates all Entity references stored inside using entity_map.

impl PartialEq<Parent> for Parent

fn eq(&self, other: &Parent) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Reflect for Parentwhere Entity: Reflect,

fn type_name(&self) -> &str

Returns the type name of the underlying type.

fn get_type_info(&self) -> &'static TypeInfo

Returns the TypeInfo of the underlying type.

fn into_any(self: Box<Self>) -> Box<dyn Any>

Returns the value as a Box<dyn Any>.

fn as_any(&self) -> &dyn Any

Returns the value as a &dyn Any.

fn as_any_mut(&mut self) -> &mut dyn Any

Returns the value as a &mut dyn Any.

fn into_reflect(self: Box<Self>) -> Box<dyn Reflect>

Casts this type to a boxed reflected value.

fn as_reflect(&self) -> &dyn Reflect

Casts this type to a reflected value.

fn as_reflect_mut(&mut self) -> &mut dyn Reflect

Casts this type to a mutable reflected value.

fn clone_value(&self) -> Box<dyn Reflect>

Clones the value as a Reflect trait object.

fn set(&mut self, value: Box<dyn Reflect>) -> Result<(), Box<dyn Reflect>>

Performs a type-checked assignment of a reflected value to this value.

fn apply(&mut self, value: &dyn Reflect)

Applies a reflected value to this value.

fn reflect_ref(&self) -> ReflectRef<'_>

Returns an enumeration of “kinds” of type.

fn reflect_mut(&mut self) -> ReflectMut<'_>

Returns a mutable enumeration of “kinds” of type.

fn reflect_owned(self: Box<Self>) -> ReflectOwned

Returns an owned enumeration of “kinds” of type.

fn reflect_partial_eq(&self, value: &dyn Reflect) -> Option<bool>

Returns a “partial equality” comparison result.

fn reflect_hash(&self) -> Option<u64>

Returns a hash of the value (which includes the type).

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

Debug formatter for the value.

fn serializable(&self) -> Option<Serializable<'_>>

Returns a serializable version of the value.

impl TupleStruct for Parentwhere Entity: Reflect,

fn field(&self, index: usize) -> Option<&dyn Reflect>

Returns a reference to the value of the field with index index as a &dyn Reflect.

fn field_mut(&mut self, index: usize) -> Option<&mut dyn Reflect>

Returns a mutable reference to the value of the field with index index as a &mut dyn Reflect.

fn field_len(&self) -> usize

Returns the number of fields in the tuple struct.

fn iter_fields(&self) -> TupleStructFieldIter<'_>

Returns an iterator over the values of the tuple struct’s fields.

fn clone_dynamic(&self) -> DynamicTupleStruct
