in a proto3 .proto file, fields are not "set"; specifically,
zero length proto3 "bytes" fields are equal (nil == {}).
- Two repeated fields are equal iff their lengths are the same,
and their corresponding elements are equal (a "bytes" field,
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
rule for the scalar fields described above applies.
- Two unset fields are equal.
- Two unknown field sets are equal if their current
encoded state is equal.
- Two extension sets are equal iff they have corresponding
elements that are pairwise equal.
- Two map fields are equal iff their lengths are the same,
and they contain the same set of elements. Zero-length map
fields are equal.
- Every other combination of things are not equal.
