Struct LocalReputationConfig 

#[non_exhaustive]
pub struct LocalReputationConfig {
    pub alpha: f64,
    pub initial_score: f64,
    pub reference_bps: u64,
    pub speed_weight: f64,
    pub correctness_weight: f64,
    pub reachability_weight: f64,
    pub max_delta_per_update: f64,
    pub decay_half_life_secs: u64,
}

Tunable parameters for the local EWMA score.

Defaults follow ADR 008 §3 (α=0.1, initial=0.5, weights 40/40/20). Validation runs at LocalReputation::new; constructing an invalid config in isolation is allowed but installing it returns ConfigError.

max_delta_per_update defaults to 1.0 (no clamping) per ADR 008 §14a; operators can set it to 0.05 to enforce §8’s per-report cap without code changes.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

alpha: f64

EWMA smoothing factor: the weight given to the newest sample. Larger reacts faster and forgets faster.

initial_score: f64

Score a peer starts at, before any interaction is recorded.

reference_bps: u64

Reference throughput scoring ~1.0 under the log speed curve (was the flat saturation baseline).

speed_weight: f64

Weight of the throughput component. The three weights must sum to 1.0 or LocalReputation::new rejects the config.

correctness_weight: f64

Weight of the hash-verification component.

reachability_weight: f64

Weight of the dial-success component.

max_delta_per_update: f64

Largest score movement one report may cause. 1.0 disables the clamp; see LOCAL_SCORE_MAX_DELTA_PER_REPORT.

decay_half_life_secs: u64

Half-life (seconds) of idle-score decay toward neutral (ADR 008 §Score Decay). Each half-life halves the distance to neutral. 0 disables decay.

Implementations

impl LocalReputationConfig

pub const fn with_max_delta_per_update(self, cap: f64) -> Self

Set the per-report score-movement cap and return the config.

The struct is #[non_exhaustive], so downstream crates cannot use a struct-update literal to override a single field; this builder is how the node wiring opts into LOCAL_SCORE_MAX_DELTA_PER_REPORT. The value is validated (finite, [0.0, 1.0]) at LocalReputation::new, not here.

Trait Implementations

impl Clone for LocalReputationConfig

fn clone(&self) -> Self

Returns a duplicate of the value.

Performs copy-assignment from source.

impl Debug for LocalReputationConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Default for LocalReputationConfig

fn default() -> Self

Returns the “default value” for a type.
