|
||||
//! # 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.
|
||||
//! - `cycle_fatal`: 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/HEAD/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 [`crate::query::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.
|
||||
//!
|
||||
//! For more details, see the [rustc-dev-guide](https://rustc-dev-guide.rust-lang.org/query.html).

//! # 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.
|
||||
//! - `cycle_fatal`: 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/HEAD/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.
|
||||
//!
|
||||
//! For more details, see the [rustc-dev-guide](https://rustc-dev-guide.rust-lang.org/query.html).
