//! This contains documentation which is linked from query modifiers used in the `rustc_queries!` proc macro.
//!
//! The dummy items in this module are used to enable hover documentation for
//! modifier names in the query list, and to allow find-all-references to list
//! all queries that use a particular modifier.
#![allow(unused, non_camel_case_types)]
// FIXME: Update and clarify documentation for these modifiers.
