Struct TrafficShapingConfig 

pub struct TrafficShapingConfig {
    pub padding: PaddingPolicy,
    pub jitter_ms: u32,
    pub cover_interval_ms: u32,
}

Available on crate feature std only.

Anti-fingerprint traffic-shaping configuration (WIRE v6, direction #4). Set on an established session via PhantomSession::set_traffic_shaping. All shaping is opt-in — the default (and the field defaults here) is no shaping, so a session pays nothing unless an embedder enables it.

Currently carries the size-padding policy (deliverable (c)); the timing-jitter (d) and cover-traffic (e) knobs will be added as further fields in later phases. Padding hides the datagram size; it costs bounded (≈ ≤12% worst-case) extra bandwidth.

Fields

padding: PaddingPolicy

Size-padding policy. PaddingPolicy::None (default) = no padding; PaddingPolicy::Padme = pad each packet up to a PADÉ bucket.

jitter_ms: u32

Send-timing jitter ceiling in milliseconds (deliverable (d)). 0 (default) = no jitter; otherwise each packet waits a uniform random [0, jitter_ms] ms before it is sent, so the inter-packet timing no longer tracks the application’s writes — at a cost of up to jitter_ms of added latency.

cover_interval_ms: u32

Cover-traffic floor interval in milliseconds (deliverable (e)). 0 (default) = no cover traffic; otherwise the session maintains a minimum outbound packet rate of 1000 / cover_interval_ms packets/sec, emitting an encrypted dummy (COVER) packet whenever no packet has gone out for cover_interval_ms — hiding idle/active patterns and volume, at a steady bandwidth cost. A typical value is 100–500 ms (10–2 packets/sec).
