Struct NodeRef 

pub struct NodeRef(pub u64);

Host-neutral packed node handle. 0 is reserved for “no node”.

Tuple Fields

0: u64

Implementations

impl NodeRef

pub const NONE: NodeRef

The null handle (0), meaning “no node”.

pub fn from_entity(entity: Entity) -> Self

Wrap an entity as a packed handle.

pub fn entity(self) -> Option<Entity>

Decode to an entity, or None for the null / invalid handle or a reserved spawn token (which has no entity until command-drain).

Trait Implementations

impl Clone for NodeRef

fn clone(&self) -> NodeRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeRef

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

Formats the value using the given formatter.

impl From<Entity> for NodeRef

fn from(e: Entity) -> Self

Converts to this type from the input type.

impl PartialEq for NodeRef

fn eq(&self, other: &NodeRef) -> 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.
