Struct AdwinDetector 

pub struct AdwinDetector { /* private fields */ }

ADWIN-style streaming change-point detector.

Implementations

impl AdwinDetector

pub fn new(range: f64, delta: f64, window_cap: usize) -> RcfResult<Self>

Build a detector with caller-chosen stream amplitude.

Errors

Returns RcfError::InvalidConfig on non-finite / non- positive range, delta outside (0, 1), or window_cap < 2 · MIN_SUBWINDOW_LEN.

pub fn with_metrics_sink(self, sink: Arc<dyn MetricsSink>) -> Self

Install a metrics sink — every update emits an observed counter, and every drift fire bumps a drift-fires counter.

pub fn metrics_sink(&self) -> &Arc<dyn MetricsSink>

Read-only handle to the installed sink.

pub fn default_bounded() -> Self

Convenience: range 1.0, DEFAULT_DELTA, DEFAULT_WINDOW_CAP.

Panics

Never — the default values pass new’s validation.

pub fn len(&self) -> usize

Current window length.

pub fn is_empty(&self) -> bool

true when the window holds no observations.

pub fn drift_fires(&self) -> u64

Lifetime drift fires since construction.

pub fn mean(&self) -> f64

Running mean of the current window (empty → 0.0).

pub fn update(&mut self, value: f64) -> bool

Fold value into the window. Evaluates every split point against the Hoeffding bound; if any split flags drift, the older sub-window is dropped and the return is true. Returns false otherwise (no drift on this update).

Non-finite values are silently dropped.

pub fn reset_window(&mut self)

Drop every observation. Counters are preserved.

Trait Implementations
