Struct RoutingNode 

pub struct RoutingNode {
    pub id: Id20,
    pub addr: SocketAddr,
    pub last_seen: Instant,
    pub fail_count: u32,
    pub last_response: Option<Instant>,
    pub last_query: Option<Instant>,
}

A node in the routing table.

Fields

id: Id20

Node’s 20-byte Kademlia ID.

addr: SocketAddr

Node’s socket address.

last_seen: Instant

Timestamp of the last successful interaction.

fail_count: u32

Number of consecutive failed queries.

last_response: Option<Instant>

Timestamp of the last response received from this node.

last_query: Option<Instant>

Timestamp of the last query received from this node.

Implementations

impl RoutingNode

pub fn status(&self) -> NodeStatus

Classify this node per Kademlia liveness rules.

• Bad: fail_count >= 2
• Good: responded or sent a query within the last 15 minutes
• Questionable: otherwise

M175 BUG FIX: previously computed Instant::now() - ACTIVE_THRESHOLD, which panics during the first 15 min of process uptime (Instant monotonic clock not yet at the threshold). Reformulated to compare elapsed time forward via Instant::duration_since, which saturates at zero on clock skew. M132-class avoidance — same bug shape as the fetch_sub(1) underflow that shipped in M132.
