Struct LinkFeedback 

pub struct LinkFeedback {
    pub loss_percent: f64,
    pub rssi_dbm: f64,
    pub snr_db: f64,
    pub packets_received: u32,
    pub fec_failed: u32,
    pub bitrate_kbps: u32,
    pub has_measurement: bool,
    pub target_slot: u8,
}

A ground-measured sample of the drone’s downlink.

Fields

loss_percent: f64

Percent of expected packets that did not arrive, 0.0–100.0.

rssi_dbm: f64

Received signal strength, whole dBm (negative).

snr_db: f64

Signal-to-noise ratio in dB.

packets_received: u32

Packets decoded this interval. Zero with FLAG_HAS_MEASUREMENT clear means the receiver heard nothing at all.

fec_failed: u32

FEC blocks that could not be recovered this interval. This is the counter that distinguishes a busy-but-fine link from a lossy one, and the one the local transmit queue can never see.

bitrate_kbps: u32

Delivered application bitrate in kbps, as measured at the receiver.

has_measurement: bool

Whether the sender actually decoded anything this interval.

target_slot: u8

The fleet slot this measurement describes.

The uplink is one transmission for the whole fleet, so every drone receives every record; this is what tells a drone whether the record is about its own link. A drone acts only on its own slot.

Implementations

impl LinkFeedback

pub fn encode(&self) -> Vec<u8>

Encode as a v1 record.

Saturating conversions throughout: a nonsense input (a wild RSSI from a driver glitch, a loss above 100) clamps to the representable edge rather than wrapping into a value of the opposite meaning.

pub fn decode(buf: &[u8]) -> Result<Self, LinkFeedbackError>

Decode a v1 record. Trailing bytes are ignored; a short record is an error.
