Struct ChangeFeedThresholds 

pub struct ChangeFeedThresholds {
    pub noise_ceiling: f64,
    pub probable_floor: f64,
    pub canary_weight: f64,
    pub proxy_weight: f64,
    pub extraction_weight: f64,
}

Configurable thresholds and source weights for the ChangeDetector.

All fields default to the documented constants — DEFAULT_NOISE_CEILING, DEFAULT_PROBABLE_FLOOR, DEFAULT_CANARY_WEIGHT, DEFAULT_PROXY_WEIGHT, and DEFAULT_EXTRACTION_WEIGHT. The struct is Copy so it can live in a static configuration without a wrapper.

Example

use stygian_charon::change_feed::{
    ChangeFeedThresholds, DEFAULT_CANARY_WEIGHT, DEFAULT_NOISE_CEILING,
    DEFAULT_PROBABLE_FLOOR,
};

let thresholds = ChangeFeedThresholds::default();
assert!(thresholds.noise_ceiling > 0.0);
assert!(thresholds.probable_floor > thresholds.noise_ceiling);

let tightened = ChangeFeedThresholds::default()
    .with_noise_ceiling(0.10)
    .with_probable_floor(0.40);
assert!(tightened.noise_ceiling < 0.20);
assert!(tightened.probable_floor < 0.55);

Fields

noise_ceiling: f64

Upper edge of the Noise band (exclusive).

probable_floor: f64

Lower edge of the Probable band (inclusive).

canary_weight: f64

Source weight applied to canary-source deltas.

proxy_weight: f64

Source weight applied to proxy-source deltas.

extraction_weight: f64

Source weight applied to extraction-source deltas.

Implementations

impl ChangeFeedThresholds

pub fn with_noise_ceiling(self, ceiling: f64) -> Self

Replace the noise_ceiling. Values < 0.0, > 1.0, or NaN fall back to the documented default so the classifier cannot silently collapse the noise band.

pub fn with_probable_floor(self, floor: f64) -> Self

Replace the probable_floor. Values < 0.0, > 1.0, or NaN fall back to the documented default. Values below noise_ceiling are clamped up so the bands always retain a valid ordering.

pub fn with_canary_weight(self, weight: f64) -> Self

Replace the canary source weight. Non-finite or non-positive values fall back to the documented default.

pub fn with_proxy_weight(self, weight: f64) -> Self

Replace the proxy source weight. Non-finite or non-positive values fall back to the documented default.

pub fn with_extraction_weight(self, weight: f64) -> Self

Replace the extraction source weight. Non-finite or non-positive values fall back to the documented default.

Trait Implementations

impl Clone for ChangeFeedThresholds

fn clone(&self) -> ChangeFeedThresholds

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChangeFeedThresholds

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

Formats the value using the given formatter.

impl Default for ChangeFeedThresholds

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ChangeFeedThresholds

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ChangeFeedThresholds

fn eq(&self, other: &ChangeFeedThresholds) -> 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 ChangeFeedThresholds

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for ChangeFeedThresholds
