## Features

- **Rust bindings for pgvector**  
  - Provides native Rust types and traits to interact with PostgreSQL `pgvector` columns.

- **ORM / client support**  
  - Integrates with popular Rust PostgreSQL clients and ORMs:

    - [SQLx](https://github.com/launchbadge/sqlx)
    - [Diesel](https://github.com/diesel-rs/diesel)

- **Embedding storage**  
  - Store vector embeddings in PostgreSQL using the `pgvector` extension.

- **Similarity queries**  
  - Run similarity searches (e.g., nearest-neighbor queries) against stored vectors via supported clients/ORMs.

- **Examples included**  
  - Repository contains example projects under the `examples/` directory to demonstrate usage with different Rust database libraries.

- **Versioned and changelogged**  
  - `CHANGELOG.md` maintained for tracking changes across releases.
