Struct EntityType 

pub struct EntityType {
    pub name: String,
    pub description: Option<String>,
    pub base: Option<String>,
    pub traits: Vec<String>,
    pub subtype_of: Vec<String>,
    pub aliases: Vec<String>,
    pub exemplars: Vec<String>,
    pub negative_examples: Vec<String>,
    pub schema: Value,
}

One entity type an ontology declares ($defs/entityType in ontology.schema.json).

Fields

name: String

The entity type’s name (^[a-z][a-z0-9-]*$).

description: Option<String>

Human-readable description — the primary positive embedding signal.

base: Option<String>

Base memory type (semantic/episodic/procedural). Optional here (tolerant parse); the schema requires it for a conformant document.

traits: Vec<String>

Traits this entity type includes.

subtype_of: Vec<String>

Parent entity types this type specializes (subsumption).

aliases: Vec<String>

Synonyms and label variations (skos:altLabel analog), distinct from description. Part of the positive embedding document.

exemplars: Vec<String>

Curated canonical example phrases or instances (skos:example analog; 2-5 recommended). Part of the positive embedding document.

negative_examples: Vec<String>

Curated near-misses from the ontology’s most confusable type pairs: texts that resemble this type but do NOT denote it. Never part of the positive embedding document (see EntityType::embedding_doc); consumed by the negative-demotion-v1 gate (crate::confidence::negative_demotes): a candidate whose query sits at least as close to one of these as to the type’s positive document is barred from auto-classify eligibility. Types carrying none score exactly as before the gate existed.

schema: Value

The {required, properties} shape a finding’s entity payload is validated against.

Implementations

impl EntityType

pub fn embedding_doc(&self) -> Option<String>

Composes the positive embedding document for this entity type: description, then each alias, then each exemplar, newline-joined in that deterministic order, skipping empty strings.

Returns None when no non-empty signal exists — callers skip such types rather than embedding an empty document (generalizing the previous skip-when-no-description behavior).

negative_examples is deliberately excluded: it asserts what this type is not, and concatenating it into the positive document would poison the type’s own embedding.

Trait Implementations

impl Clone for EntityType

fn clone(&self) -> EntityType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EntityType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EntityType

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for EntityType

impl PartialEq for EntityType

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