Struct LinkSnapshot 

pub struct LinkSnapshot {
    pub signal_quality: Option<u8>,
    pub drop_rate: Option<f32>,
    pub mcs_norm: Option<f32>,
    pub retry_rate: Option<f32>,
    pub phy_rate_kbps: Option<u32>,
    pub class: LinkClass,
}

A normalized link-quality reading. Every field is optional because no single platform / interface exposes them all.

Fields

signal_quality: Option<u8>

Signal quality, 0..=100 (Wi-Fi). None on wired links.

drop_rate: Option<f32>

Fraction of recent packets dropped / errored at the interface, 0.0..=1.0. None if counters are unavailable.

mcs_norm: Option<f32>

Normalized current PHY rate (current TX rate / the best rate seen), 0.0..=1.0, Wi-Fi. A falling value is rate-adaptation backing off under poor radio conditions - an early loss predictor before frames drop. None off Wi-Fi.

retry_rate: Option<f32>

MAC-layer transmit retry rate (tx_retries / tx_packets), 0.0..=1.0, Wi-Fi. A climbing value is the radio struggling milliseconds before the loss reaches shard accounting. None where the OS does not expose it (Windows WLAN has no retry counter; Linux nl80211 does).

phy_rate_kbps: Option<u32>

The raw first-hop PHY rate in kbit/s (Windows ulTxRate, Linux nl80211 tx_bitrate). This is nominal - the rate a SINGLE Wi-Fi hop can carry - which the mesh-hop detector compares against the measured end-to-end BtlBw: each single-radio backhaul hop roughly halves throughput, so round(log2(nominal / BtlBw)) is the backhaul-hop count. None off Wi-Fi.

class: LinkClass

The link’s class (wired / Wi-Fi / cellular / loopback / unknown).

Implementations

impl LinkSnapshot

pub fn link_stress(&self) -> f32

Combined “link stress” in 0..=1: how degraded the link looks right now. Low signal quality, a high interface drop rate, a fallen PHY rate, and a climbing retry rate all push it up - the worst of the available signals wins. Used as a feed-forward term in the fusion controller.
