Performance regression detection

Implementations

impl PerformanceRegressionDetector

pub fn new() -> Result<Self>

pub fn new_empty() -> Self

pub fn check_regression( &mut self, kernel_name: &str, profile_data: &KernelProfileData, ) -> Result<()>

Record one real execution-time measurement and, once enough history exists, either establish this kernel’s baseline or test the recent window against it – pushing a real RegressionAlert only when the Welch’s t-test finds a statistically significant slowdown beyond alert_thresholds.minor_threshold. Never a no-op that silently discards profile_data.

pub fn get_status(&self, kernel_name: &str) -> Result<Option<RegressionStatus>>

Real regression status for kernel_name, freshly recomputed from its execution-time history against its established baseline.

Returns Ok(None) – never a fabricated “stable” status – whenever there is not yet a baseline, or not yet enough recent samples in the detection window to compare against it. A pure query: unlike Self::check_regression, it never appends to regression_alerts.
