Struct FprMonitor 

pub struct FprMonitor { /* private fields */ }

Rolling-window FPR monitor with per-category drift detection.

Implementations

impl FprMonitor

pub fn new(config: FprMonitorConfig) -> Self

Create a new monitor with the given configuration.

Pre-initialises empty windows for each configured category.

pub fn record_event( &mut self, category: &str, was_flagged: bool, confidence: f64, )

Record a detection event for the given category.

If the category was not in the initial config, it is created on the fly.

pub fn record_event_at( &mut self, category: &str, at: Instant, was_flagged: bool, confidence: f64, )

Record a detection event with an explicit timestamp (useful for testing).

pub fn current_fpr(&mut self, category: &str) -> Option<f64>

Compute the current FPR for a category within the sliding window.

Returns None if the category has no recorded events.

pub fn check_drift( &mut self, category: &str, baseline_fpr: f64, ) -> Option<FprDriftAlert>

Check whether the current FPR for category has drifted from baseline_fpr.

Returns Some(alert) when the absolute deviation exceeds the configured threshold and the window contains at least min_window_samples events. Returns None otherwise.

pub fn check_all_drift( &mut self, baselines: &HashMap<String, f64>, ) -> Vec<FprDriftAlert>

Check drift across all categories against the provided baselines.

pub fn to_security_findings(alerts: &[FprDriftAlert]) -> Vec<SecurityFinding>

Convert a slice of drift alerts into SecurityFindings.

pub fn summary(&mut self) -> FprMonitorSummary

Produce a summary of all tracked categories.

Trait Implementations

impl Debug for FprMonitor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
