Review Comment:
Do we need this?
Is only `average_byte_width` enough because `min`/`max` are tested in other
tests?

Review Comment:
Could you use the same order in `.h`?
```suggestion
left.is_average_byte_width_exact ==
right.is_average_byte_width_exact &&
left.is_min_exact == right.is_min_exact &&
left.is_max_exact == right.is_max_exact &&
