   > Thanks for spotting! I added 
[645d147](https://github.com/apache/arrow-rs/commit/645d14750c771b30d6840482cec45e6f140267f0)
 which implements the suggested fix, but happy to drop it if you'd rather that 
gets merged separately.
   
   Thanks @HippoBaro, I think it's fine to roll that up with this PR.
   
   I need to look at the benches...it's a bit surprising to me that none of the 
reader benches are showing the dramatic slowdown that the roundtrip plain case 
does. Guess I need to do more profiling. I wonder if for the 
nullable-but-no-nulls case we could happy path a check of the encoded size and 
see if it matches the expected size and skip the def level decoding. Maybe a 
cheat and see if the def levels are a single run of max_def_level 🤷
