Enum TraceMetricSpec 

pub enum TraceMetricSpec {
    EventCount {
        event_type: String,
        min: Option<u64>,
        max: Option<u64>,
    },
    ToolCallCount {
        tool: Option<String>,
        min: Option<u64>,
        max: Option<u64>,
    },
    ToolErrorRate {
        max: Option<f64>,
    },
    TurnCount {
        min: Option<u64>,
        max: Option<u64>,
    },
    LatencyMs {
        max: Option<u64>,
    },
    TokenCostMicros {
        max: Option<u64>,
    },
    RetryCount {
        max: Option<u64>,
    },
    LoopDetected {
        max_repeats: u64,
    },
    EventSequence {
        event_types: Vec<String>,
    },
}

Deterministic metric computed from the case’s trace (plus evidence).

Bounds are inclusive. A metric with neither bound set is observational: it records a value without ever failing, which is a legitimate way to collect a signal before deciding what “good” means.

Implementations

impl TraceMetricSpec

pub fn metric_id(&self) -> String

Stable id used as the metric’s storage key within one evaluator.

pub const fn requires_runtime_trace(&self) -> bool

True when the metric needs authoritative tool/retry/token data, which only a runtime-written trace can provide.
