The only options I know of for heap allocated data structures are:

- StructModel, stack allocated intended originaly for low level llvm. more info here [Interval example: Why do mutable types need more sophisticated data models?](https://numba.discourse.group/t/interval-example-why-do-mutable-types-need-more-sophisticated-data-models/150)
- StructRef, new experimental heap allocated
- jitclass heap allocated
- numpy.recarrays
- named tuple, immutable
