Struct RegimeShiftConfig 

pub struct RegimeShiftConfig {
    pub enabled: bool,
    pub cusum_k: f64,
    pub cusum_h: f64,
    pub bocpd_lambda: f64,
    pub bocpd_threshold: f64,
    pub bocpd_max_run_length: usize,
}

Configuration for CUSUM/BOCPD regime-shift detection that augments the simple sliding-window counting in the budget controller.

When enabled, the detector runs alongside the existing signal-count logic and can trigger fallback before the count threshold is reached if a statistically significant regime change is detected.

Fields

enabled: bool

Master switch — when false the detector is a no-op and the budget controller falls back to pure signal counting.

cusum_k: f64

CUSUM allowance parameter k. Determines how much the observed inter-arrival rate may deviate from baseline before the cumulative sum accumulates. Expressed in multiples of baseline sigma. Lower → more sensitive, higher → fewer false positives.

cusum_h: f64

CUSUM decision threshold h. When the cumulative sum exceeds this value a regime shift is declared. Expressed in multiples of baseline sigma.

bocpd_lambda: f64

BOCPD hazard constant lambda — the prior expected run length between change points (in number of observations). Smaller → more sensitive.

bocpd_threshold: f64

Posterior probability threshold for BOCPD. When the probability that the current run length is 0 (= a change just happened) exceeds this value the detector fires.

bocpd_max_run_length: usize

Maximum run-length horizon tracked by BOCPD to bound memory/CPU. Older run lengths are pruned each tick.

Implementations

impl RegimeShiftConfig

pub const fn for_tier(tier: ExtensionBudgetTier) -> Self

Tier-specific defaults. Strict tiers are more sensitive (lower h, lower lambda) so regime shifts are detected faster at the cost of more false positives.

Trait Implementations

impl Clone for RegimeShiftConfig

fn clone(&self) -> RegimeShiftConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RegimeShiftConfig

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

Formats the value using the given formatter.

impl Default for RegimeShiftConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RegimeShiftConfig

where RegimeShiftConfig: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RegimeShiftConfig

fn eq(&self, other: &RegimeShiftConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for RegimeShiftConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
