although represented by []byte, is not a repeated field)
and their corresponding elements are equal. Note a "bytes" field,
although represented by []byte, is not a repeated field and the

- Two unset fields are equal.
- Two unknown field sets are equal if their current

- Two extension sets are equal iff they have corresponding

- Two map fields are equal iff their lengths are the same,
