The compiler configuration

Fields

opts: Options

Command line options

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

cfg! configuration in addition to the default ones

crate_check_cfg: CheckCfg

input: Input

output_dir: Option<PathBuf>

output_file: Option<OutFileName>

ice_file: Option<PathBuf>

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

locale_resources: &'static [&'static str]

lint_caps: FxHashMap<LintId, Level>

parse_sess_created: Option<Box<dyn FnOnce(&mut ParseSess) + Send>>

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

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)>

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.

expanded_args: Vec<String>

All commandline args used to invoke the compiler, with @file args fully expanded. This will only be used within debug info, e.g. in the pdb file on windows This is mainly useful for other tools that reads that debuginfo to figure out how to call the compiler with the same arguments.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
