ludus::foundation::identity::PersistentObjectKey¶

Struct

Durable identity of one object within one instance scope.

Used in saves, undo records and durable object links. Ten placements of one prefab share SourceObjectId values but have different InstanceId values, so each key names a different object.

Declared in modules/foundation/identity/include/ludus/foundation/identity/uuid.hpp

#include <ludus/foundation/identity/uuid.hpp>

struct ludus::foundation::identity::PersistentObjectKey final
