   Does these benchmarks also include writing to the buffers, or only allocating/deallocating? 
   
   I ask because I already used some sort of wrapper around a `Vec`. This is just a wrapper around a rust `Vec` that has overwritten `reserve` to use Arrows memory aligned allocation.
   
   However, for writing and indexing it uses the methods default to `Vec`. I found this to be a lot faster for creating Arrow arrays. I use it when I know I don't have null values.
