Combining Type Handles

Unity Engine

I have a decent number of jobs that share the same set of type handles. I would like to combine them into a single struct like:

public struct CombinedTypeHandles<T> where T : struct
{
  public ComponentTypeHandle<A> ATypeHandle;
  public ComponentTypeHandle<B> BTypeHandle;
  public ComponentTypeHandle<C> CTypeHandle;
  public ComponentTypeHandle<T> TTypeHandle;
}

Will this cause issues with concurrent access? I assume I can’t mark the outer struct as [ReadOnly] in a job, but if I construct each type handle with the correct isReadOnly argument will ECS/Burst still optimize access?

I’m not 100% sure, and this is something I need to experiment with more, but I think job-related attributes stack recursively, so adding [ReadOnly] on an outer struct applies to all nested NativeContainers inside the struct.
