Expand description

Information on the rustc executable

Fields§

§path: PathBuf

The location of the exe

§wrapper: Option<PathBuf>

An optional program that will be passed the path of the rust exe as its first argument, and rustc args following this.

§workspace_wrapper: Option<PathBuf>

An optional wrapper to be used in addition to rustc.wrapper for workspace crates

§verbose_version: String

Verbose version information (the output of rustc -vV)

§version: Version

The rustc version (1.23.4-beta.2), this comes from verbose_version.

§host: InternedString

The host triple (arch-platform-OS), this comes from verbose_version.

§commit_hash: Option<String>

The rustc full commit hash, this comes from verbose_version.

§cache: Mutex<Cache>

Implementations§

source§

impl Rustc

source

pub fn new( path: PathBuf, wrapper: Option<PathBuf>, workspace_wrapper: Option<PathBuf>, rustup_rustc: &Path, cache_location: Option<PathBuf>, gctx: &GlobalContext, ) -> CargoResult<Rustc>

Runs the compiler at path to learn various pieces of information about it, with an optional wrapper.

If successful this function returns a description of the compiler along with a list of its capabilities.

source

pub fn process(&self) -> ProcessBuilder

Gets a process builder set up to use the found rustc version, with a wrapper if Some.

source

pub fn workspace_process(&self) -> ProcessBuilder

Gets a process builder set up to use the found rustc version, with a wrapper if Some.

source

pub fn process_no_wrapper(&self) -> ProcessBuilder

source

pub fn cached_output( &self, cmd: &ProcessBuilder, extra_fingerprint: u64, ) -> CargoResult<(String, String)>

Gets the output for the given command.

This will return the cached value if available, otherwise it will run the command and cache the output.

extra_fingerprint is extra data to include in the cache fingerprint. Use this if there is other information about the environment that may affect the output that is not part of cmd.

Returns a tuple of strings (stdout, stderr).

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.
