Function encode_batches 

pub fn encode_batches(batches: &[RecordBatch]) -> Result<Vec<u8>, IpcError>

Encode multiple RecordBatches sharing a schema as one IPC stream.

Useful for procedure plugins that ship a series of yielded rows in one call. All batches must use the same schema (Arrow IPC stream invariant).

Errors

• IpcError::EmptyBatchInput if batches is empty.
• IpcError::Arrow if the writer rejects the batches.
