Ben Kietzman commented on ARROW-6772:
-------------------------------------
Use the `util::EqualityComparable` mixin defined in
https://github.com/apache/arrow/pull/5621
At the same time it'd be useful to incorporate the `util::ToStringOstreamable`
mixin (introduced in the same PR)
> [C++] Add operator== for interfaces with an Equals() method

> A common pattern in tests is {{ASSERT_TRUE(schm->Equals(*other)}}. The
> addition of overloaded equality operators will allow this o be written
> {{ASSERT_EQ(*schm, *other)}}, which is more idiomatic GTEST usage and will
> allow more informative assertion failure messages.
