Defines the various compiler queries. //! -//! For more information on the query system, see -//! ["Queries: demand-driven compilation"](https://rustc-dev-guide.rust-lang.org/query.html). -//! This chapter includes instructions for adding new queries. +//! # The rustc Query System: Query Definitions and Modifiers +//! +//! The core processes in rustc are shipped as queries. Each query is a demand-driven function from some key to a value. +//! The execution result of the function is cached and directly read during the next request, thereby improving compilation efficiency. +//! Some results are saved locally and directly read during the next compilation, which are core of incremental compilation. +//! +//! ## How to Read This Module +//! +//! Each `query` block in this file defines a single query, specifying its key and value types, along with various modifiers. +//! These query definitions are processed by the [`rustc_macros`], which expands them into the necessary boilerplate code +//! for the query system—including the [`Providers`] struct (a function table for all query implementations, where each field is +//! a function pointer to the actual provider), caching, and dependency graph integration. +//! **Note:** The `Providers` struct is not a Rust trait, but a struct generated by the `rustc_macros` to hold all provider functions. +//! The `rustc_macros` also supports a set of **query modifiers** (see below) that control the behavior of each query. +//! +//! The actual provider functions are implemented in various modules and registered into the `Providers` struct +//! during compiler initialization (see [`rustc_interface::passes::DEFAULT_QUERY_PROVIDERS`]). +//! +//! [`rustc_macros`]: https://doc.rust-lang.org/nightly/nightly-rustc/rustc_macros/index.html +//! [`rustc_interface::passes::DEFAULT_QUERY_PROVIDERS`]: ../../rustc_interface/passes/static.DEFAULT_QUERY_PROVIDERS.html +//! +//! ## Query Modifiers +//! +//! Query modifiers are special flags that alter the behavior of a query. They are parsed and processed by the `rustc_macros` +//! The main modifiers are: +//! +//! - `desc { ... }`: Sets the human-readable description for diagnostics and profiling. Required for every query. +//! - `arena_cache`: Use an arena for in-memory caching of the query result. +//! - `cache_on_disk_if { ... }`: Cache the query result to disk if the provided block evaluates to true. +//! - `fatal_cycle`: If a dependency cycle is detected, abort compilation with a fatal error. +//! - `cycle_delay_bug`: If a dependency cycle is detected, emit a delayed bug instead of aborting immediately. +//! - `cycle_stash`: If a dependency cycle is detected, stash the error for later handling. +//! - `no_hash`: Do not hash the query result for incremental compilation; just mark as dirty if recomputed. +//! - `anon`: Make the query anonymous in the dependency graph (no dep node is created). +//! - `eval_always`: Always evaluate the query, ignoring its dependencies and cached results. +//! - `depth_limit`: Impose a recursion depth limit on the query to prevent stack overflows. +//! - `separate_provide_extern`: Use separate provider functions for local and external crates. +//! - `feedable`: Allow the query result to be set from another query ("fed" externally). +//! - `return_result_from_ensure_ok`: When called via `tcx.ensure_ok()`, return `Result<(), ErrorGuaranteed>` instead of `()`. +//! If the query needs to be executed and returns an error, the error is returned to the caller. +//! Only valid for queries returning `Result<_, ErrorGuaranteed>`. +//! +//! For the up-to-date list, see the `QueryModifiers` struct in +//! [`rustc_macros/src/query.rs`](https://github.com/rust-lang/rust/blob/master/compiler/rustc_macros/src/query.rs) +//! and for more details in incremental compilation, see the +//! [Query modifiers in incremental compilation](https://rustc-dev-guide.rust-lang.org/queries/incremental-compilation-in-detail.html#query-modifiers) section of the rustc-dev-guide. +//! +//! ## Query Expansion and Code Generation +//! +//! The [`rustc_macros::rustc_queries`] macro expands each query definition into: +//! - A method on [`TyCtxt`] (and [`TyCtxtAt`]) for invoking the query. +//! - Provider traits and structs for supplying the query's value. +//! - Caching and dependency graph integration. +//! - Support for incremental compilation, disk caching, and arena allocation as controlled by the modifiers. +//! +//! [`rustc_macros::rustc_queries`]: ../../rustc_macros/macro.rustc_queries.html +//! +//! The macro-based approach allows the query system to be highly flexible and maintainable, while minimizing boilerplate. +//! +//!
