Struct SceneEntityReference 

pub struct SceneEntityReference(/* private fields */);

A unique reference for a named entity in a scene. Usually used by bevy_scene in generated code

Hashed here should allow implementing compile-time hashing in the future

The uniqueness of this is ensured by the following factors:

• macro invocation location: filename, line and column
• the name_id should uniquely identify a name in the individual macros scope
• runtime, per-scope counter for each runtime call (usually from a static AtomicU64)

Implementations

impl SceneEntityReference

pub fn new( (file, line, column): (&'static str, usize, usize), name_id: usize, runtime: u64, ) -> Self

Create a new SceneEntityReference from the invocation location, runtime time, and a local (per-macro) counter for names

Methods from Deref<Target = Hashed<InnerSceneEntityReference>>

pub fn hash(&self) -> u64

The pre-computed hash.

Trait Implementations

impl Clone for SceneEntityReference

fn clone(&self) -> SceneEntityReference

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SceneEntityReference

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

Formats the value using the given formatter.

impl Deref for SceneEntityReference

type Target = Hashed<InnerSceneEntityReference>

The resulting type after dereferencing.

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

Dereferences the value.

impl Display for SceneEntityReference

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

Formats the value using the given formatter.

impl Equivalent<Hashed<InnerSceneEntityReference>> for SceneEntityReference

fn equivalent(&self, key: &Hashed<InnerSceneEntityReference>) -> bool

Compare self to key and return true if they are equal.

impl Hash for SceneEntityReference

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SceneEntityReference

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

Tests for self and other values to be equal, and is used by ==.

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

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