Function random_jitter 

pub fn random_jitter(max_ms: u32) -> Duration

Available on crate feature std only.

Anti-fingerprint timing jitter (WIRE v6, deliverable (d)): a uniform random delay in [0, max_ms] milliseconds to add before a send, so the inter-packet timing no longer tracks the application’s write pattern. Returns Duration::ZERO when max_ms == 0 (jitter off). Opt-in; it trades up to max_ms of added latency per packet for timing-correlation resistance.
