Implementations

impl AlertRuntime

pub fn build(cfg: &AlertsCfg) -> Self

Compile from config. enabled folds in “has a non-empty webhook_url” so a misconfigured switch (on, but no URL) is inert rather than trying to POST nowhere on every crossing.

pub fn disabled() -> Self

An inert runtime (alerting off) — the default when [alerts] is absent.

pub fn decide_budget(&self, budget: &str, ratio: f64) -> bool

Decide whether a budget’s ratio should fire an alert now, updating the edge-trigger state: fire only on the transition into the alert zone (was-below → now at/above the threshold); reset when it drops back below so a later crossing re-alerts. Pure of IO, so the dedup logic is directly testable.

pub fn fire_budget_alert(&self, budget: &str, ratio: f64)

Fire a Slack-compatible budget alert when the ratio first crosses the threshold. No-op unless enabled and the crossing is fresh. Fire-and-forget — any webhook error is swallowed at debug.
