Struct EmbeddingIndex 

pub struct EmbeddingIndex { /* private fields */ }

Persistent embedding index.

Serialized to disk via bincode for fast startup. Rebuilds only when skill content changes (tracked via content_hash).

Implementations

impl EmbeddingIndex

pub async fn build( registry: &SkillRegistry, provider: &dyn EmbeddingProvider, weights: ComponentWeights, ) -> Result<Self, EmbedError>

Build index from registry using the given embedding provider.

Embeds all skills in parallel where possible.

pub fn load_cached( path: &Path, registry: &SkillRegistry, ) -> Result<Option<Self>, EmbedError>

Load from disk cache. Returns None if cache is stale or doesn’t exist.

pub fn save(&self, path: &Path) -> Result<(), EmbedError>

Save to disk.

pub fn query( &self, query_embedding: &Embedding, top_k: usize, ) -> Vec<ScoredSkill>

Query: return top-k skills by similarity.

pub fn query_adaptive( &self, query_embedding: &Embedding, min_score: f32, max_k: usize, gap_threshold: f32, ) -> Vec<ScoredSkill>

Query with adaptive k: return skills above threshold, with automatic gap detection.

pub fn model_id(&self) -> &str

Get the model ID this index was built with.

pub fn built_at(&self) -> SystemTime

Get when this index was built.

pub fn len(&self) -> usize

Number of skills in the index.

pub fn is_empty(&self) -> bool

Check if the index is empty.

pub fn skill_names(&self) -> Vec<&SkillName>

Get all skill names in the index.

pub fn get(&self, name: &SkillName) -> Option<&SkillEmbeddings>

Get embeddings for a specific skill.
