//! # ringDB
//!
//! A vector database specialised for **ring queries** in high-dimensional spaces.
//!
//! Instead of nearest-neighbour search, ringDB retrieves all vectors whose
//! Euclidean distance to a query lies within a specified interval `[d-λ, d+λ]`.
//!
//! ## Quick start
//!
//! ```
//! use ringdb::{RingDb, RingDbConfig, RingQuery};
//!
//! let mut db = RingDb::new(RingDbConfig::new(4)).unwrap();
//! db.add_vector(&[1.0f32, 0.0, 0.0, 0.0], ()).unwrap();
//! db.add_vector(&[0.0, 5.0, 0.0, 0.0], ()).unwrap();
//!
//! let db = db.build().unwrap();
//! let result = db.query(&RingQuery { query: &[0.0f32; 4], d: 1.0, lambda: 0.1 }).unwrap();
//! // result.ids contains IDs of all vectors at distance ≈ 1.0 from origin
//! ```
