Struct RelayEnvelope 

pub struct RelayEnvelope {
    pub message_id: MessageId,
    pub hop_count: u8,
    pub max_hops: u8,
    pub origin_node: NodeId,
    pub flags: RelayFlags,
    pub payload: Vec<u8>,
}

A relay envelope wrapping a document for multi-hop transmission

Fields

message_id: MessageId

Unique message identifier for deduplication

hop_count: u8

Current hop count (increments with each relay)

max_hops: u8

Maximum allowed hops (TTL)

origin_node: NodeId

Original sender node ID

flags: RelayFlags

Envelope flags

payload: Vec<u8>

The wrapped payload (typically an encrypted document)

Implementations

impl RelayEnvelope

pub fn new(origin_node: NodeId, payload: Vec<u8>) -> Self

Create a new relay envelope for a payload

pub fn broadcast(origin_node: NodeId, payload: Vec<u8>) -> Self

Create with broadcast flag

pub fn with_max_hops(self, max_hops: u8) -> Self

Create with custom max hops

pub fn can_relay(&self) -> bool

Check if this envelope can be relayed further

pub fn remaining_hops(&self) -> u8

Get remaining hops

pub fn relay(&self) -> Option<Self>

Create a relay copy with incremented hop count

Returns None if TTL expired.

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

Encode to bytes for transmission

pub fn decode(data: &[u8]) -> Option<Self>

Decode from bytes

pub fn is_relay_envelope(data: &[u8]) -> bool

Check if data starts with relay envelope marker
