Struct EntityIndex 

pub struct EntityIndex(pub u32);

Per-user dense index for a GlobalEntity known to a UserDiffHandler.

Phase 8.1 Stage A introduces this newtype as the in-process key for dirty-set tracking and (eventually) packed mask storage. Each user’s UserDiffHandler issues one EntityIndex per GlobalEntity it observes via crate::KeyGenerator32, recycling on deregister_component once the entity has no remaining components in the user’s receiver map. u32 instead of u16 because the index space is per-user (16K indices isn’t always enough at multi-thousand entity scopes) and because KeyGenerator’s u16 wrap-around bug was already noted as a follow-up item.

Wire-format independent. This index never crosses the wire; it’s purely an in-memory shortcut so dirty queues and (Stage B) bit-vec membership tests can use Vec-indexed operations instead of HashMap probes.

Trait Implementations

impl Clone for EntityIndex

fn clone(&self) -> EntityIndex

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EntityIndex

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

Formats the value using the given formatter.

impl From<EntityIndex> for u32

fn from(value: EntityIndex) -> Self

Converts to this type from the input type.

impl From<u32> for EntityIndex

fn from(value: u32) -> Self

Converts to this type from the input type.

impl Hash for EntityIndex

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 EntityIndex

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