Struct TransactionReader 

pub struct TransactionReader<'a> { /* private fields */ }

Reader for transaction data from Arrow batches.

Provides efficient access to transaction fields without copying data from the underlying Arrow columnar format. Each reader is bound to a specific row in the batch.
