Struct Rustc

pub struct Rustc {
    pub target: TargetSelection,
    pub build_compiler: Compiler,
    crates: Vec<String>,
}

Build rustc using the passed build_compiler.

• Makes sure that build_compiler has a standard library prepared for its host target, so that it can compile build scripts and proc macros when building this rustc.
• Makes sure that build_compiler has a standard library prepared for target, so that the built rustc can link to it and use it at runtime.

Fields

target: TargetSelection

The target on which rustc will run (its host).

build_compiler: Compiler

The previous compiler used to compile this rustc.

crates: Vec<String>

Whether to build a subset of crates, rather than the whole compiler.

This should only be requested by the user, not used within bootstrap itself. Using it within bootstrap can lead to confusing situation where lints are replayed in two different steps.

Implementations

impl Rustc

pub fn new(build_compiler: Compiler, target: TargetSelection) -> Self

Trait Implementations

impl Clone for Rustc

fn clone(&self) -> Rustc

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Rustc

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Rustc

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Rustc

fn eq(&self, other: &Rustc) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Step for Rustc

fn run(self, builder: &Builder<'_>) -> Self::Output

Builds the compiler.

This will build the compiler for a particular stage of the build using the build_compiler targeting the target architecture. The artifacts created will also be linked into the sysroot directory.

const IS_HOST: bool = true

If this value is true, then the values of run.target passed to the make_run function of this Step will be determined based on the --host flag. If this value is false, then they will be determined based on the --target flag.

const DEFAULT: bool = false

Whether this step is run by default as part of its respective phase, as defined by the describe macro in Builder::get_step_descriptions.

type Output = BuiltRustc

Result type of Step::run.

fn should_run(run: ShouldRun<'_>) -> ShouldRun<'_>

Determines if this Step should be run when given specific paths (e.g., x build $path).

fn make_run(run: RunConfig<'_>)

Called directly by the bootstrap Step handler when not triggered indirectly by other Steps using Builder::ensure. For example, ./x.py test bootstrap runs this for test::Bootstrap. Similarly, ./x.py test runs it for every step that is listed by the describe macro in Builder::get_step_descriptions.

fn metadata(&self) -> Option<StepMetadata>

Returns metadata of the step, for tests

impl Eq for Rustc

impl StructuralPartialEq for Rustc

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.
