Struct GlobalEntityMap 

pub struct GlobalEntityMap<E: Copy + Eq + Hash + Send + Sync> { /* private fields */ }

Bidirectional map between world-local entities and their stable GlobalEntity identifiers.

Implementations

impl<E: Copy + Eq + Hash + Send + Sync> GlobalEntityMap<E>

pub fn new() -> Self

Creates an empty map with no entity registrations.

pub fn entity_count(&self) -> usize

Returns the number of world entities currently registered in the map.

Trait Implementations

impl<E: Copy + Eq + Hash + Send + Sync> Default for GlobalEntityMap<E>

fn default() -> Self

Returns the “default value” for a type.

impl<E: Copy + Eq + Hash + Send + Sync> EntityAndGlobalEntityConverter<E> for GlobalEntityMap<E>

fn global_entity_to_entity( &self, global_entity: &GlobalEntity, ) -> Result<E, EntityDoesNotExistError>

Resolves global_entity to the corresponding world-local entity E, or returns an error if not found.

fn entity_to_global_entity( &self, world_entity: &E, ) -> Result<GlobalEntity, EntityDoesNotExistError>

Resolves a world-local entity to its stable GlobalEntity identifier, or returns an error if not found.

impl<E: Copy + Eq + Hash + Send + Sync> GlobalEntitySpawner<E> for GlobalEntityMap<E>

fn spawn( &mut self, world_entity: E, remote_entity_opt: Option<RemoteEntity>, ) -> GlobalEntity

Registers world_entity in the map, reusing a reserved GlobalEntity for remote_entity_opt if one exists.

fn reserve_global_entity(&mut self, remote_entity: RemoteEntity) -> GlobalEntity

Pre-allocates a GlobalEntity slot for remote_entity before the local world entity is spawned.

fn despawn_by_global(&mut self, global_entity: &GlobalEntity)

Removes the mapping keyed by global_entity, panicking if it does not exist.

fn despawn_by_world(&mut self, world_entity: &E)

Removes the mapping keyed by world_entity, panicking if it does not exist.

fn to_converter(&self) -> &dyn EntityAndGlobalEntityConverter<E>

Returns self as an EntityAndGlobalEntityConverter reference for read-only lookups.
