Struct RegressionDetector 

pub struct RegressionDetector { /* private fields */ }

Compares profiling measurements against a stored baseline and emits alerts.

Implementations

impl RegressionDetector

pub fn new(config: RegressionConfig) -> Self

pub fn detect( &self, current: &[PerfMeasurement], baseline: &PerfBaseline, ) -> Vec<RegressionAlert>

Detect regressions by comparing current measurements to the baseline.

For each named component that appears in both sets the detector computes:

• mean current value vs. baseline mean
• optional z-score significance check (when baseline has ≥ 2 points)

Returns every alert whose absolute regression percentage exceeds config.min_regression_pct.

pub fn report(&self, alerts: &[RegressionAlert]) -> String

Render alerts as a human-readable text report.

pub fn save_baseline(&self, baseline: &PerfBaseline, path: &Path) -> Result<()>

Persist a PerfBaseline as JSON to path.

pub fn load_baseline(&self, path: &Path) -> Result<PerfBaseline>

Load a PerfBaseline from a JSON file.

pub fn create_baseline( measurements: Vec<PerfMeasurement>, description: &str, ) -> PerfBaseline

Build a new PerfBaseline from a set of measurements.

pub fn recommendations(&self, alerts: &[RegressionAlert]) -> Vec<String>

Generate actionable recommendations for a list of alerts.
