Struct AlertRule 

pub struct AlertRule {
    pub name: String,
    pub severity: AlertSeverity,
    pub kind: AlertRuleKind,
    pub cooldown: Duration,
}

A configured alerting rule.

Each rule carries a unique name, a AlertSeverity, the monitored AlertRuleKind, and a cooldown that suppresses repeat alerts while the rule remains continuously tripped.

Fields

name: String

Unique rule identifier (also used as the alert’s rule_name).

severity: AlertSeverity

Severity attached to alerts produced by this rule.

kind: AlertRuleKind

The condition being monitored.

cooldown: Duration

Minimum time between successive firing alerts for this rule.

Implementations

impl AlertRule

pub fn failure_rate( name: impl Into<String>, severity: AlertSeverity, trip_threshold: f64, ) -> Self

Build a failure-rate rule. By default the clear threshold equals the trip threshold (no hysteresis), the window is 60s, min_samples is 1 and the cooldown is 60s; adjust with the builder methods.

pub fn queue_depth( name: impl Into<String>, severity: AlertSeverity, trip_depth: u64, ) -> Self

Build a queue-depth rule. Clear depth defaults to the trip depth.

pub fn no_heartbeat( name: impl Into<String>, severity: AlertSeverity, timeout: Duration, ) -> Self

Build a no-heartbeat rule.

pub fn with_cooldown(self, cooldown: Duration) -> Self

Set the cooldown between repeated firing alerts.

pub fn with_clear_threshold(self, clear: f64) -> Self

Set the clear threshold for a failure-rate rule (enables hysteresis).

pub fn with_window(self, window: Duration) -> Self

Set the sliding window for a failure-rate rule.

pub fn with_min_samples(self, min_samples: u64) -> Self

Set the minimum samples for a failure-rate rule.

pub fn with_clear_depth(self, clear: u64) -> Self

Set the clear depth for a queue-depth rule (enables hysteresis).

pub fn for_queue(self, queue: impl Into<String>) -> Self

Watch a specific queue for a queue-depth rule.
