Struct AresVectorStore 

pub struct AresVectorStore { /* private fields */ }

Available on crate feature ares-vector only.

Pure Rust vector store using HNSW algorithm.

This is the default vector store for Ares, providing:

• Zero external dependencies (no protobuf, no GRPC)
• Embedded operation (no separate server)
• Optional persistence to disk
• High-performance approximate nearest neighbor search

Implementations

impl AresVectorStore

pub async fn new(path: Option<String>) -> Result<Self>

Create a new AresVector store.

Arguments

• path - Optional path to persist data. If None, operates in-memory.

Errors

Returns an error if the database cannot be initialized or loaded.

Trait Implementations

impl Default for AresVectorStore

fn default() -> Self

Returns the “default value” for a type.
