> If two fields only differ by metadata the error message isn't very informative:
> {code}
> ../src/arrow/testing/gtest_util.cc:147: Failure
> Failed
> left field: ints: int8 not null
> right field: ints: int8 not null
> {code}
> Perhaps {{DataType::ToString}}, {{Field::ToString}} and {{Schema::ToString}} could get an optional flag to display metadata?
