1//! Macros for generating unsupported domain stub implementations.
2//!
3//! These macros eliminate boilerplate when a provider doesn't support a particular
4//! domain. Instead of manually writing trait implementations that return
5//! `EveryMapError::unsupported_domain`, use the appropriate macro.
