Description

This should apply primarly to DataType, Field, and Schema. It should not try to print things like metadata and nullability. This is not meant for serialization but quick glance.

 

i32
list<i32>
dict<utf8,i8>
struct<<a,i32>,<b,struct<<n,utf8>>>>
schema<<a,i32>>

Once we have that, we can have a small print diagnostic to array/tables like R.
