Implementations§

source§

impl<'a, 'b> RunCompiler<'a, 'b>

source

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

source

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

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 + Send + Sync>> ) -> &mut Self

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> ) -> Self

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<()>

Parse args and run the compiler.
