+//! Data access layer for iMessage chat.db
+//!
+//! This library provides a read-only interface to query messages from a
+//! specific conversation.
+//!
+//! # Safety
+//!
+//! All database connections are opened in read-only mode to prevent any
+//! accidental modifications to your iMessage database.
+//!
+//! # Example
+//!
+//! ```no_run
+//! use libmarathon::ChatDb;
+//!
+//! let db = ChatDb::open("chat.db")?;
+//!
+//! // Get all messages from January 2024 to now
+//! let messages = db.get_our_messages(None, None)?;
+//! println!("Found {} messages", messages.len());
+//! # Ok::<(), libmarathon::ChatDbError>(())
+//! ```
