Enum FetchSubgroupMode 

pub enum FetchSubgroupMode {
    Zero,
    SameAsPrior,
    PriorPlusOne,
    Present,
}

How an Object on a draft-16 fetch stream states its Subgroup ID.

The two least significant bits of Serialization Flags form this field; draft-16 Section 10.4.4.1 Table 5 lists the four readings. Three of them put no Subgroup ID on the wire.

Variants

Zero

0x00 — the Subgroup ID is zero.

SameAsPrior

0x01 — the Subgroup ID is the prior Object’s Subgroup ID.

PriorPlusOne

0x02 — the Subgroup ID is the prior Object’s Subgroup ID plus one.

Present

0x03 — the Subgroup ID field is present on the wire.
