// This example shows the basic usage of the crate:
// This transform does nothing but copy the same data from an
// input topic to an output topic.
fn main() {
    // Make sure to register your callback and perform other setup in main
    on_record_written(my_transform);
}

// This will be called for each record in the source topic.
//
// The output records returned will be written to the destination topic.
fn my_transform(event: WriteEvent, writer: &mut RecordWriter) -> Result<()> {
    writer.write(event.record)?;
    Ok(())
