To remove same type of account owning objects in one transaction

[markeddolphin]

Here, I'd like to remove array of account owning objects in one transaction programmatically.

Here is my code.

public struct Receipt has key {
   id: UID
}

public fun burn_receipts(receipts: &mut vector<Receipt>) {
    while(!vectory::is_empty(receipts)) {
        let Receipt { id } = vector::pop_back(receipts);
        id.delete();
    }
}

when I run this code, its returning UnusedvaluewithoutDrop.

Thank you for opening this issue, a team member will review it shortly. Until then, please do not interact with any users that claim to be from Sui support and do not click on any links!

@stefan-mysten I would really love to hear your suggestion on this obstacle. :)

I believe that the issue is that your Receipt type does not have a drop ability. If you want to keep it like that, you will need to transfer the receipts object (that is passed into burn_receipts function) or somehow burn it/ drop it.

The UnusedValueWithoutDrop tells you while receipts might be empty, as you deleted all its elements, it's still an object, I think. However, I don't do a lot of Move so I might be off. Hope it helps!

Maybe sui PTB could be solution I think. So instead of taking vector, I might need to create function to take Receipt and burn it in. I can call this function multiple times for the receipts I need to be burned using PTB. so It can be triggered in one transaction.
