You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: produce.rs
    path of file: ./repos/fluvio/crates/fluvio-spu-schema/tests
    
    the code of the file until where you have to start completion: use std::error::Error;
use std::io::Cursor;

use fluvio_spu_schema::produce::{DefaultProduceRequest};
use fluvio_protocol::Decoder;
use fluvio_spu_schema::Isolation;

// Test Specification:
//
// A request was encoded and written to a file, using the following code:
//
// ```rust
//     let mut batch = Batch::new();
//     batch.add_record(Record::default());
//     let records: RecordSet<RawRecords> = RecordSet {
//         batches: vec![ba
    
fn test_binary_compatibility() -> Result<(), Box<dyn Error>> {
    let old_encoded = std::fs::read("./tests/produce_request.bin")?;
    let decoded: DefaultProduceRequest =
        Decoder::decode_from(&mut Cursor::new(old_encoded), 7).expect("decoded");

    assert_eq!(decoded.timeout.as_millis(), 1000);
    assert_eq!(decoded.transactional_id, Some("transaction_id".to_owned()));
    assert_eq!(decoded.isolation, Isolation::ReadCommitted);

    assert_eq!(decoded.topics[0].name, "topic".to_owned());
    assert_eq!(decoded.topics[0].partitions[0].partition_index, 1);
    assert_eq!(decoded.topics[0].partitions[0].records.batches.len(), 1);
    Ok(())
