#![deny(unsafe_code)]

//! Local data persistence for Aranet sensor readings.
//!
//! This crate provides SQLite-based storage for Aranet sensor data,
//! enabling offline access, history caching, and efficient queries.
//!
//! # Features
//!
//! - Store current readings with timestamps
//! - Cache history records (avoid re-downloading from device)
//! - Incremental sync tracking per device
//! - Query by device, time range, with pagination
//! - Export/import support
//!
//! # Example
//!
//! ```no_run
//! use aranet_store::{Store, ReadingQuery};
//!
//! let store = Store::open_default()?;
//!
//! // Query recent readings
//! let query = ReadingQuery::new()
//!     .device("Aranet4 17C3C")
//!     .limit(10);
//! let readings = store.query_readings(&query)?;
//! # Ok::<(), aranet_store::Error>(())
//! ```
