Struct Std

pub struct Std {
    pub target: TargetSelection,
    pub 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 compiler.

Fields

target: TargetSelection

compiler: Compiler

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(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)>

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 Ord for Std

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

Restrict a value to a certain interval.

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 PartialOrd for Std

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

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

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.

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).

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 ONLY_HOSTS: bool = false

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

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.
