1//! Rich type filter operators and handlers.
2//!
3//! This module provides specialized filter operators for 44 rich scalar types,
4//! enabling powerful queries like:
5//!
6//! - Extract and filter by email domain: `email.domain_eq('example.com')`
7//! - Parse and filter by VIN components: `vin.wmi_eq('1HG')`
8//! - Geographic filtering: `coordinates.distance_within(lat, lng, radius_km)`
9//! - Country lookups: `country.continent_eq('Europe')`
