json rpc – What’s one of the simplest ways to verify utilizing bitcoin core RPC if a transaction is re-orged?

My present strategy is to verify the next:

fn is_orphaned(..) {
    let res = get_raw_transaction(txid)
    return confirmations == 0 && blockhash != null
}

Is the above means appropriate? And is there a extra direct means of checking whether or not a transaction is re-orged? I’m operating bitcoin core with txindex = 1
