Struct PineconeStore 

pub struct PineconeStore { /* private fields */ }

Pinecone vector store client

Implementations

impl PineconeStore

pub fn new(api_key: impl Into<String>, host: impl Into<String>) -> Self

Create a Pinecone client.

host format: https://{index-name}.svc.{environment}.pinecone.io

pub fn build_upsert_body( docs: &[Document], vectors: &[Vec<f32>], ids: &[String], ) -> Result<Value, VectorStoreError>

Build the upsert request body, injecting each document’s text into metadata.content (only when the caller did not already set that key) and failing loudly when a vector’s metadata exceeds the 40 KiB cap.

0.25.0 B3: read-back paths recover the document text from metadata.content (PineconeStore::query); without the injection the text is silently lost on the round trip. Oversized metadata is rejected here instead of surfacing as an opaque Pinecone 400 transport error.

pub fn build_query_body(query_vec: &[f32], top_k: usize) -> Value

Build query request body (pure function, convenient for testing).

pub fn build_query_body_filtered( query_vec: &[f32], top_k: usize, filter: &MetadataFilter, ) -> Value

Build query request body with a metadata filter (pure function, convenient for testing).

S3: extends build_query_body with a Pinecone filter field, where filter_to_pinecone translates MetadataFilter → Pinecone query syntax (field name → $op value, combinations via $and/$or).

pub async fn upsert( &self, docs: &[Document], embeddings: &dyn Embeddings, ) -> Result<(), VectorStoreError>

Upsert documents (auto-embed).

pub async fn query( &self, query_vec: Vec<f32>, top_k: usize, ) -> Result<Vec<Document>, VectorStoreError>

Query similar documents.

pub async fn describe_index_stats( &self, ) -> Result<PineconeIndexStats, VectorStoreError>

Reads index statistics (the only reliable source for a true count).

The Pinecone REST API provides describe_index_stats, returning totalVectorCount.

pub async fn delete(&self, ids: &[String]) -> Result<(), VectorStoreError>

Delete by IDs.

impl VectorStore for PineconeStore

fn similarity_search_with_filter<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, query_embedding: &'life1 [f32], k: usize, filter: Option<&'life2 MetadataFilter>, ) -> Pin<Box<dyn Future<Output = Result<Vec<SearchResult>, VectorStoreError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

S3: similarity search with metadata filtering — filtering is delegated to the server (native Pinecone filter syntax).

where Self: 'async_trait, 'life0: 'async_trait,

Adds documents.

fn similarity_search<'life0, 'life1, 'async_trait>( &'life0 self, query_embedding: &'life1 [f32], k: usize, ) -> Pin<Box<dyn Future<Output = Result<Vec<SearchResult>, VectorStoreError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Searches similar documents.

fn get_document<'life0, 'life1, 'async_trait>( &'life0 self, _id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<Document>, VectorStoreError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Gets document by ID.

fn get_embedding<'life0, 'life1, 'async_trait>( &'life0 self, _id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<Vec<f32>>, VectorStoreError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Gets document embedding by ID.

fn delete_document<'life0, 'life1, 'async_trait>( &'life0 self, id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<(), VectorStoreError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Deletes document.

fn count<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = usize> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Returns document count.

fn clear<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<(), VectorStoreError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Clears store.

fn embed_query(&self) -> Option<&dyn Embeddings>

Returns this vector store’s built-in text embedder, if any.

fn similarity_search_text<'life0, 'life1, 'async_trait>( &'life0 self, query: &'life1 str, k: usize, ) -> Pin<Box<dyn Future<Output = Result<Vec<SearchResult>, VectorStoreError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Text similarity search: vectorizes query with the embedder returned by embed_query, then searches.

fn similarity_search_with_min_score<'life0, 'life1, 'async_trait>( &'life0 self, query_embedding: &'life1 [f32], k: usize, min_score: Option<f32>, ) -> Pin<Box<dyn Future<Output = Result<Vec<SearchResult>, VectorStoreError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Similarity search with a minimum score threshold.
