The compiler configuration

Fields

opts: Options

Command line options

crate_cfg: FxHashSet<(String, Option<String>)>

cfg! configuration in addition to the default ones

input: Input

input_path: Option<PathBuf>

output_dir: Option<PathBuf>

output_file: Option<PathBuf>

file_loader: Option<Box<dyn FileLoader + Send + Sync>>

diagnostic_output: DiagnosticOutput

stderr: Option<Arc<Mutex<Vec<u8>>>>

Set to capture stderr output during compiler execution

lint_caps: FxHashMap<LintId, Level>

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 plugin registration 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, _: &mut Providers)>

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

The second parameter is local providers and the third parameter is external providers.

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

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

registry: Registry

Registry of diagnostics codes.
