Hi, is there no way for me to have a struct as a `@storage_var` if it contains an array fo felts inside ?

For e.g. if I have a struct User:
```
struct User{
  values_len: felt ,
  VALUES: felt*,
}
```

Then I need to store a mapping from User Id to Users, is it not possible ?

Is there any way to abi-encode calldata to pass to `account.execute`? Also is `contract.invoke` going to be deprecated in the future? IIRC <> mentioned something related to that at the meetup.

Is there any other way to do 2**n without using `pow.cairo`?

Is there any other way to do 2**n without using pow.cairo?

For an array in Cairo, since there is no inherent structure, removing an item from an array means all of the other items after the removed item must be moved, since this is on the blockchain that can be extremely costly. What is the best way to handle this? Should the removed item just be replaced with an empty placeholder? What is the right way to handle this?

Cairo Array Item Removal

heyy guys, running into a problem

I have this code :
```struct TokenLedger:
   member token_address : felt
   member drip_amount : Uint256
   member balance : Uint256
end

@storage_var
func tokens_ledger(index : felt) -> (tokenLedger : TokenLedger):
end```

```let (ledger : TokenLedger) = TokenLedger(token_address, drip_amount, balance)
tokens_ledger.write(index, ledger)```
But am getting this error :

```faucet.cairo:94:34: Unexpected '.' after '__main__.TokenLedger' which is struct.
let (ledger : TokenLedger)  = TokenLedger(token_detail.token_address, token_detail.drip_amount, curr_balance)
                                ^*********^

       Failed

Error in plugin Starknet: Failed compilation of 1 contract.```
