Struct RunCompiler

pub struct RunCompiler<'a> {
    pub(crate) at_args: &'a [String],
    pub(crate) callbacks: &'a mut (dyn Callbacks + Send),
    pub(crate) file_loader: Option<Box<dyn FileLoader + Send + Sync>>,
    pub(crate) make_codegen_backend: Option<Box<dyn FnOnce(&Options) -> Box<dyn CodegenBackend> + Send>>,
    pub(crate) using_internal_features: Arc<AtomicBool>,
}

This is the primary entry point for rustc.

Fields

at_args: &'a [String]

callbacks: &'a mut (dyn Callbacks + Send)

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

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

using_internal_features: Arc<AtomicBool>

Implementations

impl<'a> RunCompiler<'a>

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

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.)

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

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.

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

Parse args and run the compiler.

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.
