Typedefs

EntityId

using helios::core::types::EntityId = uint32_t

Unique identifier for an entity within an EntityPool.

Used as the index into the sparse array of an EntityPool. Combined with a VersionId in an EntityHandle, it enables safe entity references that detect stale handles after entity removal.

StrongId_t

using helios::core::types::StrongId_t = uint32_t

Underlying integer type for all strong identifiers.

`StrongId_t` is the common numeric representation used by `StrongId<Tag>` and related lookup structures (e.g., `EntityRegistry`, `LinearLookupStrategy`, `HashedLookupStrategy`). Centralising the typedef ensures a consistent width across the entire identifier subsystem.

VersionId

using helios::core::types::VersionId = uint32_t

Version number for detecting stale entity references.

Each entity slot in an EntityPool has an associated version that is incremented when the entity is removed. EntityHandles store both the EntityId and VersionId, allowing the pool to detect when a handle refers to a recycled slot.

A valid version starts at 1 (uninitialized handles have version 0).

Variables

EntityTombstone

size_t helios::core::types::EntityTombstone = std::numeric_limits<size_t>::max()

constexpr

Sentinel value indicating an invalid or removed sparse index.

Used in sparse-set data structures (e.g., EntityPool, GameObjectPool) to mark slots that do not contain valid entity references. When a slot contains this value, the corresponding entity has been removed or was never assigned.

no_init

no_init_t helios::core::types::no_init

constexpr

Tag constant for requesting uninitialized construction.

This is a convenience instance of `no_init_t` that can be passed to constructors supporting uninitialized construction.

```cpp helios::util::Guid id{helios::core::types::no_init}; ```
