Struct bootstrap::core::build_steps::compile::Rustc

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

Fields

target: TargetSelection

compiler: Compiler

The previous compiler used to compile this compiler.

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(compiler: Compiler, target: TargetSelection) -> Self

Trait Implementations

impl Clone for Rustc

fn clone(&self) -> Rustc

Returns a copy 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 Ord for Rustc

fn cmp(&self, other: &Rustc) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

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 PartialOrd for Rustc

fn partial_cmp(&self, other: &Rustc) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Step for Rustc

type Output = u32

We return the stage of the “actual” compiler (not the uplifted one).

By “actual” we refer to the uplifting logic where we may not compile the requested stage; instead, we uplift it from the previous stages. Which can lead to bootstrap failures in specific situations where we request stage X from other steps. However we may end up uplifting it from stage Y, causing the other stage to fail when attempting to link with stage X which was never actually built.

fn run(self, builder: &Builder<'_>) -> u32

Builds the compiler.

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

const ONLY_HOSTS: bool = true

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

const DEFAULT: bool = false

Whether this step is run by default as part of its respective phase. true here can still be overwritten by should_run calling default_condition.

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

When bootstrap is passed a set of paths, this controls whether this rule will execute. However, it does not get called in a “default” context when we are not passed any paths; in that case, make_run is called directly.

fn make_run(run: RunConfig<'_>)

Builds up a “root” rule, either as a default rule or from a path passed to us.

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.
