//! Nothing in here is written by hand. `cargo xtask gen-grammar` produces it from
//! `crates/rudb-parse/grammar`, and `cargo xtask gen-grammar --check` runs in the gate and fails

//! `build.rs` so that the diff of a grammar bump shows what actually changed, which is the whole
//! point of pinning it. `spec/20-the-grammar.md` section 5.
