Struct PatternMetricsResult 

pub struct PatternMetricsResult {
    pub entropy_per_category: BTreeMap<String, f64>,
    pub total_entropy: f64,
    pub convention_drift: f64,
    pub convention_drift_per_category: BTreeMap<String, f64>,
}

Pattern metrics derived from the catalog — carried in every snapshot.

Computed by sdivi_core::compute_pattern_metrics or populated by sdivi_pipeline::Pipeline from the full catalog.

Examples

use std::collections::BTreeMap;
use sdivi_snapshot::snapshot::PatternMetricsResult;

let m = PatternMetricsResult {
    entropy_per_category: BTreeMap::new(),
    total_entropy: 0.0,
    convention_drift: 0.0,
    convention_drift_per_category: BTreeMap::new(),
};
assert_eq!(m.total_entropy, 0.0);

Fields

entropy_per_category: BTreeMap<String, f64>

Shannon entropy of pattern fingerprints per category.

total_entropy: f64

Sum of per-category entropies.

convention_drift: f64

Average fraction of distinct fingerprints per category (0–1).

Defined as: for each category, distinct_fingerprints / total_instances, then average across all categories. 0.0 when no instances exist.

convention_drift_per_category: BTreeMap<String, f64>

Per-category fraction of distinct fingerprints: distinct / total for each category.

Source of truth for per-category override filtering in compute_thresholds_check. The scalar convention_drift is the average of this map’s values.

Trait Implementations

impl Clone for PatternMetricsResult

fn clone(&self) -> PatternMetricsResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PatternMetricsResult

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

Formats the value using the given formatter.

impl Default for PatternMetricsResult

fn default() -> PatternMetricsResult

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PatternMetricsResult

fn deserialize<__D>( __deserializer: __D, ) -> Result<PatternMetricsResult, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PatternMetricsResult

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
