Struct HelloPayload 

pub struct HelloPayload {
    pub node_name: Name,
    pub served_prefixes: Vec<Name>,
    pub capabilities: u8,
    pub neighbor_diffs: Vec<NeighborDiff>,
    pub public_key: Option<Bytes>,
    pub unicast_port: Option<u16>,
}

Payload carried in the Content of a hello Data packet.

Fields

node_name: Name

Mandatory: the sender’s NDN node name.

served_prefixes: Vec<Name>

Prefixes this node produces (for service discovery bootstrapping).

capabilities: u8

Advisory capability flags (see CAP_* constants).

neighbor_diffs: Vec<NeighborDiff>

SWIM gossip diffs piggybacked on this hello.

public_key: Option<Bytes>

Raw 32-byte Ed25519 public key (self-attesting signed hellos). When present, the hello Data is signed by the corresponding private key and receivers can verify without any certificate infrastructure.

unicast_port: Option<u16>

UDP unicast listen port. When present, receivers should create their unicast face to <sender-ip>:<unicast_port> rather than to the source port of the hello packet (which may be the multicast port).

Implementations

impl HelloPayload

pub fn new(node_name: Name) -> Self

Construct a minimal hello payload with just the node name.

pub fn encode(&self) -> Bytes

Encode the payload to wire bytes (the Content TLV value).

pub fn decode(content: &Bytes) -> Option<Self>

Decode a HelloPayload from Content bytes.

Returns None if the NODE-NAME field is missing or malformed; unknown TLV types are silently skipped for forward compatibility.

Trait Implementations

impl Clone for HelloPayload

fn clone(&self) -> HelloPayload

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HelloPayload

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

Formats the value using the given formatter.
