Question about excluding Module members from auto generated Record

[med1844]

I have a use case where I need to mark certain Module members as "constants" that shouldn't be included in the corresponding Record. In my case, such members are a custom struct containing multiple constant tensors.

Currently, I see that:

1. We have Param<Tensor<B, D>> to explicitly mark tensors as parameters
2. But there doesn't seem to be a way to do the reverse - marking members to be excluded from Record

Questions:

1. Is there an existing way to exclude Module members from Record?
2. If not, does this mean we need to manually define the Record and implement load_record/into_record?

Alternative Design Suggestion

It might be more intuitive if:

• Tensor<B, D> was treated as a parameter by default
• We had something like Const<T> to mark any type T as "constant that can be recreated when instantiating a module"
  • This would work for both tensors and custom modules

Would love to hear if there are existing solutions I missed, or any guidance on implementing this functionality.

I think Ignored<T> should do the trick here. Also seems very similar in spirit to your suggested Const<T>.
