Struct Std

pub struct Std {
    pub target: TargetSelection,
    pub build_compiler: Compiler,
    crates: Vec<String>,
    force_recompile: bool,
    extra_rust_args: &'static [&'static str],
    is_for_mir_opt_tests: bool,
}

Build a standard library for the given target using the given build_compiler.

Fields

target: TargetSelection

build_compiler: Compiler

Compiler that builds the standard library.

crates: Vec<String>

Whether to build only a subset of crates in the standard library.

This shouldn’t be used from other steps; see the comment on Rustc.

force_recompile: bool

When using download-rustc, we need to use a new build of std for running unit tests of Std itself, but we need to use the downloaded copy of std for linking to rustdoc. Allow this to be overridden by builder.ensure from other steps.

extra_rust_args: &'static [&'static str]

is_for_mir_opt_tests: bool

Implementations

impl Std

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

pub fn force_recompile(self, force_recompile: bool) -> Self

pub fn is_for_mir_opt_tests(self, is_for_mir_opt_tests: bool) -> Self

pub fn extra_rust_args(self, extra_rust_args: &'static [&'static str]) -> Self

fn copy_extra_objects( &self, builder: &Builder<'_>, compiler: &Compiler, target: TargetSelection, ) -> Vec<(PathBuf, DependencyType)>

pub fn should_be_uplifted_from_stage_1( builder: &Builder<'_>, stage: u32, ) -> bool

Returns true if the standard library should be uplifted from stage 1.

Uplifting is enabled if we’re building a stage2+ libstd and full bootstrap is disabled.

Trait Implementations

impl Clone for Std

fn clone(&self) -> Std

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Std

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

Formats the value using the given formatter.

impl Hash for Std

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 Std

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

type Output = Option<BuildStamp>

Build stamp of std, if it was indeed built or uplifted.

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

Builds the standard library.

This will build the standard library 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 DEFAULT: bool = true

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

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

const IS_HOST: bool = false

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.

impl Eq for Std

impl StructuralPartialEq for Std

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.
