Struct FetchObjectLocation 

pub struct FetchObjectLocation {
    pub group_id: u64,
    pub subgroup_id: Option<u64>,
    pub object_id: u64,
    pub publisher_priority: Option<u8>,
    pub end_of_range: Option<FetchEndOfRange>,
}

One fetch object’s Location and priority, with every field the flags left off the wire filled in from the Object before it.

Fields

group_id: u64

Resolved absolute Group ID.

subgroup_id: Option<u64>

Resolved absolute Subgroup ID, and None for an Object whose Forwarding Preference is Datagram — draft-16 Section 10.2.1 omits the Subgroup ID for those, and Section 10.4.4.1 marks them with bit 0x40.

object_id: u64

Resolved absolute Object ID.

publisher_priority: Option<u8>

Publisher Priority, and None when no Object on the stream so far has stated one.

That happens only after a FetchEndOfRange marker, which carries no Priority of its own and leaves the running value alone; any other first Object with no Priority is refused by FetchObjectReader::resolve. Draft-16 Section 11.1.1.1 supplies the fallback for the gap — a subscription has Publisher Priority 128 when DEFAULT PUBLISHER PRIORITY is omitted — and it is left to the caller rather than substituted here, so that the stream never said stays distinguishable from “the stream said 128”.

end_of_range: Option<FetchEndOfRange>

The Table 4 marker this Object is, or None for an ordinary Object.

When set, this Location is the far end of a span: Section 10.4.4.2 reads every Location between the previously serialized Object, if any, and this one — inclusive — as non-existent or unknown.
