Struct rustc_driver::RunCompiler

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

This is the primary entry point for rustc.

Fields

at_args: &'a [String]

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

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

emitter: Option<Box<dyn Write + Send>>

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

Implementations

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

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

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.

Used by cg_clif.

pub fn set_emitter(
    &mut self,
    emitter: Option<Box<dyn Write + Send>>
) -> &mut Self

Emit diagnostics to the specified location.

Used by RLS.

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.

Used by RLS.

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

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.
