Struct RustcLink

struct RustcLink {
    pub compiler: Compiler,
    pub previous_stage_compiler: Compiler,
    pub target: TargetSelection,
    crates: Vec<String>,
}

RustcLink copies all of the rlibs from the rustc build into the previous stage’s sysroot. This is necessary for tools using rustc_private, where the previous compiler will build a tool against the next compiler. To build a tool against a compiler, the rlibs of that compiler that it links against must be in the sysroot of the compiler that’s doing the compiling.

Fields

compiler: Compiler

The compiler whose rlibs we are copying around.

previous_stage_compiler: Compiler

This is the compiler into whose sysroot we want to copy the rlibs into.

target: TargetSelection

crates: Vec<String>

Not actually used; only present to make sure the cache invalidation is correct.

Implementations

impl RustcLink

fn from_rustc(rustc: Rustc, host_compiler: Compiler) -> Self

Trait Implementations

impl Clone for RustcLink

fn clone(&self) -> RustcLink

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RustcLink

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

Formats the value using the given formatter.

impl Hash for RustcLink

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 RustcLink

fn eq(&self, other: &RustcLink) -> 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 RustcLink

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

Same as std_link, only for librustc

type Output = ()

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).

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.

const ONLY_HOSTS: bool = false

If true, then this rule should be skipped if –target was specified, but –host was not

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.

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.
