Implementations§

source§

impl<'a> RunCompiler<'a>

source

pub fn new( at_args: &'a [String], callbacks: &'a mut (dyn Callbacks + Send), ) -> RunCompiler<'a>

source

pub fn set_make_codegen_backend( &mut self, make_codegen_backend: Option<Box<dyn FnOnce(&Options) -> Box<dyn CodegenBackend> + Send>>, ) -> &mut RunCompiler<'a>

Set a custom 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.)

source

pub fn set_file_loader( &mut self, file_loader: Option<Box<dyn FileLoader + Sync + Send>>, ) -> &mut RunCompiler<'a>

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.)

source

pub fn set_using_internal_features( self, using_internal_features: Arc<AtomicBool>, ) -> RunCompiler<'a>

Set the session-global flag that checks whether internal features have been used, suppressing the message about submitting an issue in ICEs when enabled.

source

pub fn run(self) -> Result<(), ErrorGuaranteed>

Parse args and run the compiler.
