TransactionData The TransactionData struct contains important information about a transaction in the Fuel network. The id field is the transaction hash, which is a 32-byte string. The receipts field contains a list of Receipts, which are generated by a Fuel node during the execution of a Sway smart contract; you can find more information in the Receipts section.

}TransactionStatus TransactionStatus refers to the status of a Transaction in the Fuel network.
