Struct PeerQuality 

pub struct PeerQuality {
    pub throughput: Estimate,
    pub rtt: Estimate,
    pub reliability: Reliability,
    pub samples: u64,
    pub in_flight: u32,
}

The learned per-peer quality model (SPEC §3.1). Refined only from measured outcomes.

Fields

throughput: Estimate

Achievable throughput (bytes/sec), learned (SPEC §3.2).

rtt: Estimate

Round-trip / time-to-first-byte latency (ms), learned (SPEC §3.2).

reliability: Reliability

Success probability in [0,1], learned (SPEC §3.4).

samples: u64

Count of measured outcomes folded in (confidence, SPEC §3.1).

in_flight: u32

Ranges currently assigned to this peer (live in-flight, not learned — SPEC §3.1, §5.3).

Implementations

impl PeerQuality

pub const fn cold() -> Self

A cold quality model: no samples, unknown throughput/RTT/reliability (SPEC §3.5). Neither optimistic nor pessimistic — uncertain.

pub fn is_cold(&self) -> bool

Whether this peer is cold (no measured outcomes yet), qualifying for exploration (SPEC §3.5, §4.4-E).

pub fn confidence(&self) -> f64

A confidence weight in [0,1] — rises with samples, so a well-measured peer’s point estimate is trusted more than a barely-sampled one (SPEC §3.2, §4.4-E). A saturating curve: a handful of samples already gives meaningful confidence, many samples approach full confidence.

pub fn observe_throughput(&mut self, bps: f64)

Fold one measured throughput sample (bytes/sec) into the model.

pub fn observe_rtt(&mut self, ms: f64)

Fold one measured RTT sample (ms) into the model.

pub fn observe_result(&mut self, ok: bool, hard: bool)

Fold a success/failure into the reliability model (hard = a verification failure, SPEC §3.4).

pub fn bump_samples(&mut self)

Increment the count of measured outcomes (confidence).
