Struct DiscoveryConfig

}

Discovery protocol (node.discovery.*).

Fields

ttl: u8

Hop limit for LookupRequest flood (node.discovery.ttl).

attempt_timeouts_secs: Vec<u64>

Per-attempt timeouts in seconds (node.discovery.attempt_timeouts_secs). Each entry is the time to wait for a response before sending the next LookupRequest (with a fresh request_id). Sequence length determines the total number of attempts before declaring the destination unreachable. Default [1, 2, 4, 8] gives 4 attempts and a 15s total budget.

recent_expiry_secs: u64

Dedup cache expiry in seconds (node.discovery.recent_expiry_secs).

backoff_base_secs: u64

Base backoff after lookup failure in seconds (node.discovery.backoff_base_secs). Doubles per consecutive failure up to backoff_max_secs. Defaults to 0 (no post-failure suppression); the per-attempt sequence in attempt_timeouts_secs provides the only retry pacing.

backoff_max_secs: u64

Maximum backoff cap in seconds (node.discovery.backoff_max_secs).

forward_min_interval_secs: u64

Minimum interval between forwarded lookups for the same target in seconds (node.discovery.forward_min_interval_secs). Defense-in-depth against misbehaving nodes.

nostr: NostrDiscoveryConfig

Nostr-mediated overlay endpoint discovery.

lan: LanDiscoveryConfig

mDNS / DNS-SD peer discovery on the local link. Identity surface is a strict subset of what nostr.advertise already publishes publicly, so there’s no marginal privacy cost; the latency win for same-LAN peers is large (sub-second pairing, no relay).
