Struct RoutingEntry 

pub struct RoutingEntry {
    pub peer_id: String,
    pub multiaddrs: Vec<String>,
    pub latency_ms: Option<u64>,
    pub last_seen: Instant,
    pub ttl: Duration,
}

A single provider record held inside the routing table.

Fields

peer_id: String

Libp2p peer identifier (string form).

multiaddrs: Vec<String>

Known multiaddrs for this peer.

latency_ms: Option<u64>

Observed round-trip latency in milliseconds, if measured.

last_seen: Instant

Monotonic timestamp of the last time this entry was refreshed.

ttl: Duration

How long this entry remains valid after creation / refresh.

Implementations

impl RoutingEntry

pub fn new(peer_id: String, multiaddrs: Vec<String>) -> Self

Create a new entry with default TTL and no latency measurement.

pub fn with_ttl(peer_id: String, multiaddrs: Vec<String>, ttl: Duration) -> Self

Create an entry with a custom TTL.

pub fn with_latency( peer_id: String, multiaddrs: Vec<String>, latency_ms: u64, ttl: Duration, ) -> Self

Create an entry with observed latency and a custom TTL.

pub fn affinity_score(&self) -> f64

Compute a floating-point affinity score used for ranking.

Formula:

• Base score: 1.0
• Subtract 0.001 × latency_ms if latency is known.
• Subtract 0.5 if less than 10 % of the TTL remains.
• Add 0.2 if the entry was seen within the last 5 minutes.

Higher scores rank first.

pub fn is_expired(&self, now: Instant) -> bool

Return true when the entry’s TTL has elapsed relative to now.

Trait Implementations

impl Clone for RoutingEntry

fn clone(&self) -> RoutingEntry

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

Performs copy-assignment from source.

impl Debug for RoutingEntry

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