Enum AnyFetchGroupOrder 

pub enum AnyFetchGroupOrder {
    Ascending,
    Descending,
}

The order a fetch response’s groups arrive in.

Drafts 18 and 19 encode an Object’s Group ID as a difference from the previous Object’s, and the direction that difference moves is the fetch’s Group Order — which is settled by the control exchange that opened the fetch and never appears on the data stream. A reader therefore has to be told, and telling it wrong does not fail to parse: every Object decodes under a Group ID walking the wrong way.

Ignored on drafts 07-17, whose fetch objects state their Group ID outright.

Variants

Ascending

Group IDs increase along the stream; a difference is added.

Descending

Group IDs decrease along the stream; a difference is subtracted.
