Crate ares_store 

Database Clients and Vector Stores

This module provides database abstractions for:

• PostgreSQL: Relational database for conversations, users, etc.
• Vector Stores: Multi-provider vector database support

Relational Database

The [PostgresClient] provides async access to PostgreSQL for:

• User management (registration, authentication)
• Conversation storage and retrieval
• Message history
• User memory (facts, preferences)

Vector Store Providers

The following vector store backends are supported:

• ares-vector (default) - Pure Rust embedded HNSW vector database
• lancedb - Serverless, embedded vector database (may have build issues on Windows)
• qdrant - High-performance vector search engine
• pgvector - PostgreSQL extension
• chromadb - Simple embedding database
• pinecone - Managed cloud service

Enable providers via Cargo features:

ares = { version = "*", features = ["ares-vector", "qdrant"] }

Example

use ares::db::{PostgresClient, VectorStore, AresVectorStore};

// Relational database
let db = PostgresClient::new("postgres://user:pass@localhost:5432/ares").await?;
let user = db.get_user_by_id(user_id).await?;

// Vector store
let vector_store = AresVectorStore::new("./vectors").await?;
vector_store.upsert("docs", embeddings, metadata).await?;
let results = vector_store.search("docs", query_embedding, 10).await?;
