Enum ParamEncoding 

enum ParamEncoding {
    Varint,
    Uint8,
    Location,
    LengthPrefixed,
    TrackNamespaceValue,
    LocationFilter,
    FillParameters,
}

How a parameter value is encoded on the wire.

Variants

Varint

Bare varint.

Uint8

Single byte (uint8).

Location

Two consecutive varints (group, object).

LengthPrefixed

Length-prefixed bytes.

TrackNamespaceValue

A Track Namespace as defined in draft-23 Section 8.7: a varint field count followed by that many length-prefixed fields.

The fifth value encoding draft-23 Section 9.19 lists: “Track Namespace: A sequence of length-prefixed fields (Section 8.7)”. TRACK_NAMESPACE_PREFIX is the parameter that uses it; the field count is the only length the wire carries.

LocationFilter

A Location Filter Type followed by the zero to four vi64 fields that type names (draft-23 Section 9.19.9).

None of the five encodings Section 9.19 lists fits it. The parameter definition states its own structure, and that structure has no length: the type is the only thing that says where the value ends.

FillParameters

A Number of Parameters count and that many parameters (Section 9.19.15). Like a LOCATION_FILTER it has no length, so the inner parameters are read one by one to find where it ends.
