rule_id.rs

1//! Rule identifiers: one variant per requirement the specs define.
2//!
3//! A rule ID is an address — `domain:rule` — that a failure message cites and
4//! a reader follows to the sentence that binds. This enum is the compile-time
5//! form of every `` ### `domain:rule` `` heading under the canon's specs; a
6//! parity test in `embedded` holds the two sets equal. Rule prose lives in
7//! the specs, never here.
