A decoded NDNLPv2 LpPacket.

Fields

fragment: Option<Bytes>

The network-layer fragment (Interest or Data wire bytes). None for bare Ack-only packets (no payload).

nack: Option<NackReason>

Nack header — present when this LpPacket carries a Nack.

congestion_mark: Option<u64>

Hop-by-hop congestion mark (0 = no congestion).

sequence: Option<u64>

Fragment sequence number (for reassembly ordering).

frag_index: Option<u64>

Zero-based index of this fragment within the original packet.

frag_count: Option<u64>

Total number of fragments the original packet was split into.

acks: Vec<u64>

Piggybacked Ack TxSequences (NDNLPv2 reliability).

pit_token: Option<Bytes>

PIT token (opaque, 1-32 bytes).

incoming_face_id: Option<u64>

Incoming face ID (local control header).

next_hop_face_id: Option<u64>

Next-hop face ID (local control header).

cache_policy: Option<CachePolicyType>

Cache policy.

tx_sequence: Option<u64>

Reliability TxSequence (0x0348) — distinct from fragmentation Sequence (0x51).

non_discovery: bool

NonDiscovery flag (presence = true).

prefix_announcement: Option<Bytes>

Prefix announcement (raw Data bytes).

Implementations

impl LpPacket

pub fn decode(raw: Bytes) -> Result<Self, PacketError>

Decode an LpPacket from raw wire bytes.

The input must start with TLV type 0x64 (LP_PACKET).

impl LpPacket

pub fn is_fragmented(&self) -> bool

Returns true if this LpPacket is a fragment of a larger packet.

pub fn is_ack_only(&self) -> bool

Returns true if this LpPacket is a bare Ack (no payload fragment).

Trait Implementations

impl Debug for LpPacket

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
