[optional] Either

1. NOLINT these
2. Make the mesh not a ref (it's computed using slice_through anyways) and the DataVector non-owning
3. Use pointers

@nilsvu I think this is code for ID or something? I don't know what it's supposed to do so could you take over addressing this? I remember looking at the code and the current use-case is technically fine.

This is for BNS ID. Yes I can address this in a separate PR.

Good enough for me
