Function record_batch_iterator_next 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn record_batch_iterator_next(
    iter: *mut RecordBatchIter,
    out: *mut CSlice,
)

Get the next record batch from the iterator.

The output record batch is written to the buffer pointed to by out. The caller is responsible for deallocating the output buffer.

Safety

iter and out must be valid pointers.
