Enum VectorStoreProvider 

pub enum VectorStoreProvider {
    AresVector {
        path: Option<String>,
    },
    InMemory,
}

Configuration for vector store providers.

Each variant contains the necessary configuration to connect to a specific vector database backend.

Variants

AresVector

Available on crate feature ares-vector only.

AresVector - Pure Rust embedded vector database with HNSW (default).

No native dependencies, compiles anywhere Rust does. Data stored locally with optional persistence.

Fields

path: Option<String>

Path to the data directory (None for in-memory).

InMemory

In-memory vector store for testing.

Data is not persisted and will be lost when the process exits.

Implementations

impl VectorStoreProvider

pub async fn create_store(&self) -> Result<Box<dyn VectorStore>>

Create a vector store instance from this provider configuration.

Errors

Returns an error if the connection fails or the provider feature is not enabled.

pub fn from_env() -> Self

Create a provider from environment variables.

Checks for provider-specific environment variables in order:

1. ARES_VECTOR_PATH → AresVector (default)
2. LANCEDB_PATH → LanceDB
3. QDRANT_URL → Qdrant
4. PGVECTOR_URL → pgvector
5. CHROMADB_URL → ChromaDB
6. PINECONE_API_KEY → Pinecone
7. Falls back to AresVector in-memory or InMemory
