The compiler configuration

Fields§

§opts: Options

Command line options

§crate_cfg: Vec<String>

Unparsed cfg! configuration in addition to the default ones.

§crate_check_cfg: Vec<String>§input: Input§output_dir: Option<PathBuf>§output_file: Option<OutFileName>§ice_file: Option<PathBuf>§file_loader: Option<Box<dyn FileLoader + Send + Sync>>

Load files from sources other than the file system.

Has no uses within this repository, but may be used in the future by bjorn3 for “hooking rust-analyzer’s VFS into rustc at some point for running rustc without having to save”. (See #102759.)

§lint_caps: FxHashMap<LintId, Level>§psess_created: Option<Box<dyn FnOnce(&mut ParseSess) + Send>>

This is a callback from the driver that is called when ParseSess is created.

§track_state: Option<Box<dyn FnOnce(&Session) + Send>>

This is a callback to track otherwise untracked state used by the caller.

You can write to sess.env_depinfo and sess.file_depinfo to track env vars and files.

§register_lints: Option<Box<dyn Fn(&Session, &mut LintStore) + Send + Sync>>

This is a callback from the driver that is called when we’re registering lints; it is called during lint loading when we have the LintStore in a non-shared state.

Note that if you find a Some here you probably want to call that function in the new function being registered.

§override_queries: Option<fn(&Session, &mut Providers)>

This is a callback from the driver that is called just after we have populated the list of queries.

§extra_symbols: Vec<&'static str>

An extra set of symbols to add to the symbol interner, the symbol indices will start at PREDEFINED_SYMBOLS_COUNT

§make_codegen_backend: Option<Box<dyn FnOnce(&EarlySession) -> Box<dyn CodegenBackend> + Send>>

This is a callback from the driver that is called to create a codegen backend.

Has no uses within this repository, but is used by bjorn3 for “the hotswapping branch of cg_clif” for “setting the codegen backend from a custom driver where the custom codegen backend has arbitrary data.” (See #102759.)

§using_internal_features: &'static AtomicBool

The inner atomic value is set to true when a feature marked as internal is enabled. Makes it so that “please report a bug” is hidden, as ICEs with internal features are wontfix, and they are usually the cause of the ICEs.
