options: Option<TransactionOptions>

Required. Options for the new transaction.

request_options: Option<RequestOptions>

Common options for this request. Priority is ignored for this request. Setting the priority in this request_options struct doesn’t do anything. To set the priority for a transaction, set it on the reads and writes that are part of this transaction instead.
