   Hi @frolovdev. I'm afraid I'm away from a computer for the next few days, 
but taking a cursory look, lines like
   
   ```
           let entry_len = rep_levels.iter().filter(|level| **level == 
0).count();
   ```
   
   Are not able to correctly handle the case of a MapArrayReader inside another 
list, as it starts a new run when the repetition level is 0, as opposed to the 
repetition level of the map array (which will only be 0 if it is at the root).
