Global configuration for the entire build and/or bootstrap.

This structure is parsed from config.toml, and some of the fields are inferred from git or build-time parameters.

Note that this structure is not decoded directly into, but rather it is filled out from the decoded forms of the structs below. For documentation each field, see the corresponding fields in config.example.toml.

Implementations

impl Config

pub fn default_opts() -> Config

pub fn parse(args: &[String]) -> Config

pub(crate) fn parse_inner( args: &[String], get_toml: impl Fn(&Path) -> TomlConfig ) -> Config

pub fn dry_run(&self) -> bool

pub(crate) fn try_run(&self, cmd: &mut Command) -> Result<(), ()>

👎Deprecated: use Builder::try_run instead where possible

Runs a command, printing out nice contextual information if it fails. Exits if the command failed to execute at all, otherwise returns its status.success().

pub(crate) fn git(&self) -> Command

A git invocation which runs inside the source directory.

Use this rather than Command::new("git") in order to support out-of-tree builds.

pub(crate) fn test_args(&self) -> Vec<&str>

pub(crate) fn args(&self) -> Vec<&str>

pub(crate) fn artifact_version_part(&self, commit: &str) -> String

Bootstrap embeds a version number into the name of shared libraries it uploads in CI. Return the version it would have used for the given commit.

pub fn bindir_relative(&self) -> &Path

Try to find the relative path of bindir, otherwise return it in full.

pub fn libdir_relative(&self) -> Option<&Path>

Try to find the relative path of libdir.

pub(crate) fn ci_llvm_root(&self) -> PathBuf

The absolute path to the downloaded LLVM artifacts.

pub(crate) fn ci_rustc_dir(&self) -> PathBuf

Directory where the extracted rustc-dev component is stored.

pub(crate) fn llvm_link_shared(&self) -> bool

Determine whether llvm should be linked dynamically.

If false, llvm should be linked statically. This is computed on demand since LLVM might have to first be downloaded from CI.

pub(crate) fn download_rustc(&self) -> bool

Return whether we will use a downloaded, pre-compiled version of rustc, or just build from source.

pub(crate) fn download_rustc_commit(&self) -> Option<&str>

pub(crate) fn initial_rustfmt(&self) -> Option<PathBuf>

pub fn verbose(&self, f: impl Fn())

Runs a function if verbosity is greater than 0

pub fn sanitizers_enabled(&self, target: TargetSelection) -> bool

pub fn needs_sanitizer_runtime_built(&self, target: TargetSelection) -> bool

pub fn any_sanitizers_to_build(&self) -> bool

pub fn profiler_path(&self, target: TargetSelection) -> Option<&str>

pub fn profiler_enabled(&self, target: TargetSelection) -> bool

pub fn any_profiler_enabled(&self) -> bool

pub fn submodules(&self, rust_info: &GitInfo) -> bool

pub fn codegen_backends(&self, target: TargetSelection) -> &[String]

pub fn default_codegen_backend(&self, target: TargetSelection) -> Option<String>

pub fn check_stage0_version( &self, program_path: &Path, component_name: &'static str )

fn download_ci_rustc_commit( &self, download_rustc: Option<StringOrBool> ) -> Option<String>

Returns the commit to download, or None if we shouldn’t download CI artifacts.

fn parse_download_ci_llvm( &self, download_ci_llvm: Option<StringOrBool>, asserts: bool ) -> bool

pub fn last_modified_commit( &self, modified_paths: &[&str], option_name: &str, if_unchanged: bool ) -> Option<String>

Returns the last commit in which any of modified_paths were changed, or None if there are untracked changes in the working directory and if_unchanged is true.

impl Config

Generic helpers that are useful anywhere in bootstrap.

pub fn is_verbose(&self) -> bool

pub(crate) fn create(&self, path: &Path, s: &str)

pub(crate) fn remove(&self, f: &Path)

pub(crate) fn tempdir(&self) -> PathBuf

Create a temporary directory in out and return its path.

NOTE: this temporary directory is shared between all steps; if you need an empty directory, create a new subdirectory inside it.

pub(crate) fn check_run(&self, cmd: &mut Command) -> bool

Runs a command, printing out nice contextual information if it fails. Returns false if do not execute at all, otherwise returns its status.success().

fn should_fix_bins_and_dylibs(&self) -> bool

Whether or not fix_bin_or_dylib needs to be run; can only be true on NixOS

fn fix_bin_or_dylib(&self, fname: &Path)

Modifies the interpreter section of ‘fname’ to fix the dynamic linker, or the RPATH section, to fix the dynamic library search path

This is only required on NixOS and uses the PatchELF utility to change the interpreter/RPATH of ELF executables.

Please see https://nixos.org/patchelf.html for more information

fn download_file(&self, url: &str, dest_path: &Path, help_on_error: &str)

fn download_http_with_retries( &self, tempfile: &Path, url: &str, help_on_error: &str )

fn unpack(&self, tarball: &Path, dst: &Path, pattern: &str)

pub(crate) fn verify(&self, path: &Path, expected: &str) -> bool

Returns whether the SHA256 checksum of path matches expected.

impl Config

Functions that are only ever called once, but named for clarify and to avoid thousand-line functions.

pub(crate) fn download_clippy(&self) -> PathBuf

pub(crate) fn maybe_download_rustfmt(&self) -> Option<PathBuf>

NOTE: rustfmt is a completely different toolchain than the bootstrap compiler, so it can’t reuse target directories or artifacts

pub(crate) fn ci_rust_std_contents(&self) -> Vec<String>

pub(crate) fn ci_rustc_dev_contents(&self) -> Vec<String>

fn ci_component_contents(&self, stamp_file: &str) -> Vec<String>

pub(crate) fn download_ci_rustc(&self, commit: &str)

pub(crate) fn download_beta_toolchain(&self)

fn download_toolchain( &self, version: &str, sysroot: &str, stamp_key: &str, extra_components: &[&str], download_component: fn(_: &Config, _: String, _: &str, _: &str) )

fn download_ci_component( &self, filename: String, prefix: &str, commit_with_assertions: &str )

Download a single component of a CI-built toolchain (not necessarily a published nightly).

fn download_component( &self, mode: DownloadSource, filename: String, prefix: &str, key: &str, destination: &str )

pub(crate) fn maybe_download_ci_llvm(&self)

fn download_ci_llvm(&self, llvm_sha: &str)

Trait Implementations

impl Clone for Config

fn clone(&self) -> Config

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for Config

fn default() -> Config

Returns the “default value” for a type.

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.
