Module manager 

World-level entity ownership and lookup.

Steel deliberately uses a simpler loaded/simulated split than vanilla’s entity section manager. The manager owns runtime entity lookup regardless of chunk load state; chunks are still the persistence boundary, and only full simulated chunks tick entities.

Modules

benchmark_support

Fixtures for benchmarking the world entity manager without a live world.

entries 🔒

Slot storage for entity entries, so queries index a Vec instead of hashing each candidate.

spatial_query 🔒

Ordered query hits gathered from already sorted spatial cells.

Structs

ChunkEntityLoadResult

Entity changes produced when a chunk becomes loaded.

ChunkEntityUnloadStart

Entity changes produced when a chunk starts unloading.

EntityEntry 🔒

EntityLifecycleChanges

Entity lifecycle changes caused by manager membership or visibility updates.

EntityMoveUpdate

Section/chunk membership update caused by a committed entity move.

EntityQueryOrder 🔒

EntitySpatialCell 🔒

EntitySpatialCellBounds 🔒

EntityTickList 🔒

IndexedOrderedEntityIds 🔒

Append-ordered IDs with indexed unlinking for large lifecycle lists.

IndexedOrderedEntityIdsIter 🔒

ManagerState 🔒

OrderedEntityIdNode 🔒

OrderedEntityIds 🔒

RetainedSpatialCells 🔒

Bounds an index update can leave in place when an entity’s old and new cells overlap.

SpatialCellEntities 🔒

TickContext 🔒

Pre-tick manager state resolved under one state lock.

UnsavedEntityReport

Saveable entity that could not be persisted by a chunk save pass.

WorldEntityManager

Central world entity manager.

Enums

AddEntityError

Error returned when adding an entity to the runtime world fails.

EntityCollisionCandidates 🔒

Candidate set used by vanilla movement’s entity-shape collision query.

EntityMoveError

Error returned when a live entity move cannot be committed.

EntityOwnership

Whether the manager owns persistence for an entity.

EntityVisibility

Entity visibility for a chunk column.
