  Small helper method to make downcasting an Array return an error.
• mask_nulls 🔒
  Merge the provided null buffer with the existing array’s null buffer, if any.
• preserves_order
  Returns true iff the ordering of the “raw” and Persist-encoded versions of this columm would match: ie. sort(encode(column)) == encode(sort(column)). This encoding has been designed so that this is true for many types.
• scalar_type_to_encoder 🔒
  Small helper function to create a DatumColumnEncoder from a ScalarType
