AllocLeakDetector

Struct AllocLeakDetector 

Source
pub struct AllocLeakDetector { /* private fields */ }
Expand description

Sequential allocation leak detector combining CUSUM and e-process.

Feed per-frame allocation counts via [observe]. The detector maintains running estimates of the baseline mean and standard deviation, then applies both CUSUM and an e-process test to the standardised residuals.

An alert triggers when either detector fires. The evidence ledger records all intermediate state for post-mortem diagnostics.

Implementations§

Source§

impl AllocLeakDetector

Source

pub fn new(config: LeakDetectorConfig) -> Self

Create a new detector with the given configuration.

Source

pub fn observe(&mut self, value: f64) -> LeakAlert

Observe a new allocation count (or byte total) for this frame.

Returns a LeakAlert indicating whether the detector triggered.

Source

pub fn e_value(&self) -> f64

Current e-process value (evidence against H₀).

Source

pub fn cusum_upper(&self) -> f64

Current CUSUM upper statistic.

Source

pub fn cusum_lower(&self) -> f64

Current CUSUM lower statistic.

Source

pub fn mean(&self) -> f64

Current mean estimate.

Source

pub fn sigma(&self) -> f64

Current σ estimate.

Source

pub fn frames(&self) -> usize

Total frames observed.

Source

pub fn ledger(&self) -> &[EvidenceEntry]

Access the full evidence ledger.

Source

pub fn threshold(&self) -> f64

E-process threshold (1/α).

Source

pub fn reset(&mut self)

Reset detector state (preserves config).
