Struct FeatureVector 

pub struct FeatureVector {
    pub entity_id: EntityId,
    pub features: HashMap<String, f64>,
    pub normalized_features: HashMap<String, f64>,
    pub metadata: HashMap<String, Value>,
    pub refactoring_suggestions: Vec<RefactoringSuggestion>,
}

Container for an entity’s computed feature vector.

Fields

entity_id: EntityId

Unique identifier for the entity

features: HashMap<String, f64>

Raw feature values as computed by extractors

normalized_features: HashMap<String, f64>

Normalized feature values (after scoring pipeline)

metadata: HashMap<String, Value>

Additional metadata about the entity or extraction process

refactoring_suggestions: Vec<RefactoringSuggestion>

Refactoring suggestions generated during analysis
