A [NativeContainer] that provides access to information about how Entities are stored. Entity.
EntityStorageInfoLookup is a native container that provides access to information about how Entities are stored.
You can use EntityStorageInfoLookup to look up data associated with one entity while iterating over a
different set of entities.
To get a EntityStorageInfoLookup, call ComponentSystemBase.GetEntityStorageInfoLookup.
Pass a EntityStorageInfoLookup container to a job by defining a public field of the appropriate type
in your IJob implementation. You can safely read from EntityStorageInfoLookup in any job, and the EntityStorageInfoLookup
will never write data.
If you would like to access an entity's storage information outside of a job, consider using the
EntityManager methods EntityManager.GetStorageInfo instead, to avoid the overhead
of creating a EntityStorageInfoLookup object.
