Struct WireVersionMetrics 

pub struct WireVersionMetrics { /* private fields */ }

Registry of unknown wire-version counters, keyed by (peer_node_id, message_type, version).

Designed for low-frequency events (version mismatches are rare after a successful negotiation handshake). Uses a parking_lot::RwLock-free append-only Vec behind an Arc for simplicity; contention is negligible.

Implementations

impl WireVersionMetrics

pub fn increment_unknown_version( &self, peer_node_id: u64, message_type: &'static str, version: u16, )

Increment the counter for (peer_node_id, message_type, version), creating a new bucket if this is the first observation.

pub fn snapshot(&self) -> Vec<(u64, &'static str, u16, u64)>

Return a snapshot of all counter values, sorted by (peer_node_id, message_type, version).

pub fn total(&self) -> u64

Total number of unknown-version frames seen across all buckets.
