Struct LookupResponse 

pub struct LookupResponse {
    pub request_id: u64,
    pub target: NodeAddr,
    pub path_mtu: u16,
    pub target_coords: TreeCoordinate,
    pub proof: Signature,
}

Response to a lookup request with target’s coordinates.

Routed back to the origin using the origin_coords from the request.

Fields

request_id: u64

Echoed request identifier.

target: NodeAddr

The target node.

path_mtu: u16

Minimum transport MTU along the response path.

Initialized to u16::MAX by the target. Each transit node applies path_mtu = path_mtu.min(outgoing_link_mtu) when forwarding. NOT included in the proof signature (transit annotation).

target_coords: TreeCoordinate

Target’s coordinates in the tree.

proof: Signature

Proof that target authorized this response (signature over request).

Implementations

impl LookupResponse

pub fn new( request_id: u64, target: NodeAddr, target_coords: TreeCoordinate, proof: Signature, ) -> Self

Create a new lookup response.

path_mtu is initialized to u16::MAX by the target; transit nodes reduce it as they forward.

pub fn proof_bytes( request_id: u64, target: &NodeAddr, target_coords: &TreeCoordinate, ) -> Vec<u8>

Get the bytes that should be signed as proof.

Format: request_id (8) || target (16) || coords_encoding (2 + 16×n)

pub fn encode(&self) -> Vec<u8>

Encode as wire format (includes msg_type byte).

Format: [0x31][request_id:8][target:16][path_mtu:2][target_coords_cnt:2][target_coords:16×n][proof:64]

pub fn decode(payload: &[u8]) -> Result<Self, ProtocolError>

Decode from wire format (after msg_type byte has been consumed).

Trait Implementations

impl Clone for LookupResponse

fn clone(&self) -> LookupResponse

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LookupResponse

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

Formats the value using the given formatter.
