[Ruby] StructArray#[] raises NoMethodError

    XMLWordPrintableJSON

Details

    Description

      `Arrow::StructArray` does not have `#get_value` method, and `Arrow::Array#[]` interface depends on `#get_value` method.

      And so, `StructArray` cannot access internal columns via `#[]` interface.

       

      Error message is following.

      NoMethodError: undefined method `get_value' for #<Arrow::StructArray:0x0000000001859ac0>
