> the field order can vary from objet to object so when comparing two
variants for equality the field order should not be taken into account
Hm, I assume you are talking about
> The field ids and field offsets must be in lexicographical order of the
corresponding field names in the metadata dictionary.
> However, the actual `value` entries do not need to be in any particular
order.
> This implies that the `field_offset` values may not be monotonically
increasing.
> For example, for the following object:
> ```
> {
> "c": 3,
> "b": 2,
> "a": 1
> }
> ```
> The `field_id` list must be `[<id for key "a">, <id for key "b">, <id for
key "c">]`, in lexicographical order.
> The `field_offset` list must be `[<offset for value 1>, <offset for value
2>, <offset for value 3>, <last offset>]`.
> The `value` list can be in any order.
