Struct BenchmarkGate 

pub struct BenchmarkGate { /* private fields */ }

Benchmark gate that compares measurements against thresholds.

Implementations

impl BenchmarkGate

pub fn new(gate_name: &str) -> Self

Create a new benchmark gate.

pub fn threshold(self, threshold: Threshold) -> Self

Add a threshold.

pub fn load_json(gate_name: &str, json: &str) -> Option<Self>

Load thresholds from a simple JSON map.

Expected format:

{
  "metric_name": { "budget": 123.0, "tolerance_pct": 10.0 }
}

Returns None if parsing fails.

pub fn load_baseline_json( gate_name: &str, json: &str, percentile: &str, ) -> Option<Self>

Load thresholds from FrankenTUI’s tests/baseline.json format.

This format uses percentile budgets (p99_ns) and threshold_pct:

{
  "frame_render": {
    "p99_ns": 2000000,
    "threshold_pct": 10
  }
}

Entries whose keys start with _ are skipped (metadata comments). The percentile parameter selects which budget to use (e.g., "p99_ns").

Returns None if the JSON is malformed.

pub fn evaluate(&self, measurements: &[Measurement]) -> GateResult

Evaluate measurements against thresholds.

Metrics with no matching threshold get MetricVerdict::Unchecked. Emits structured JSONL evidence via TestJsonlLogger.
