Struct TlvDecodeStage 

pub struct TlvDecodeStage {
    pub face_table: Arc<FaceTable>,
    /* private fields */
}

Decodes the raw bytes in ctx into an Interest, Data, or Nack.

Handles both bare Interest/Data packets and NDNLPv2 LpPacket-wrapped packets. LpPackets with a Nack header produce a DecodedPacket::Nack.

On success sets ctx.packet and ctx.name. On any parse failure returns Action::Drop(MalformedPacket).

Enforces /localhost scope: packets with names starting with /localhost arriving on non-local faces are dropped.

Fields

face_table: Arc<FaceTable>

Implementations

impl TlvDecodeStage

pub fn new(face_table: Arc<FaceTable>) -> Self

Create a new decode stage.

pub fn try_collect_fragment( &self, face_id: FaceId, raw: Bytes, ) -> Result<Option<Bytes>, Bytes>

Fast-path fragment collection that bypasses PacketContext creation.

If the raw bytes are a fragmented LpPacket, parses just the header fields and feeds the fragment to the per-face ReassemblyBuffer.

Returns:

• Ok(Some(bytes)) — reassembly completed, bytes is the full packet
• Ok(None) — fragment buffered, waiting for more
• Err(bytes) — not a fragment (bare packet, unfragmented LpPacket, or Nack); caller should process through the full pipeline. The original bytes are returned back.
