Review Comment:
`bool`?
Or can we use `decoder_->GetBatch()` in this method too?

Can we also show invalid position?

Review Comment:
It seems that `decoder_->GetBatch()` returns the number of read values. It
may be smaller than `max_values`. So this may cause invalid `num_values_`.

Could you try `archery lint --clang-format --fix` instead?
