Module latency_tracker 

Per-peer latency histogram tracking with percentile reporting.

This module provides fine-grained latency monitoring for each connected peer, including:

• Recording RTT measurements per peer with ring-buffer sample management
• Percentile computation with linear interpolation (p50, p95, p99, arbitrary)
• Histogram generation with configurable bucket counts
• Fastest/slowest peer ranking by mean latency
• Global aggregate statistics across all tracked peers

Example

use ipfrs_network::latency_tracker::{PeerLatencyTracker};

let mut tracker = PeerLatencyTracker::new(1000);

tracker.record("peer-1", 1_500);
tracker.record("peer-1", 2_000);
tracker.record("peer-1", 1_800);

if let Some(p99) = tracker.percentile("peer-1", 0.99) {
    println!("P99 = {} us", p99);
}

if let Some(m) = tracker.mean("peer-1") {
    println!("Mean = {:.1} us", m);
}
