Struct Rustc

pub struct Rustc {
    pub path: PathBuf,
    pub wrapper: Option<PathBuf>,
    pub workspace_wrapper: Option<PathBuf>,
    pub verbose_version: String,
    pub host: InternedString,
    /* private fields */
}

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)

host: InternedString

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

Implementations

impl Rustc

pub fn new( path: PathBuf, wrapper: Option<PathBuf>, workspace_wrapper: Option<PathBuf>, rustup_rustc: &Path, cache_location: Option<PathBuf>, ) -> 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.

pub fn process(&self) -> ProcessBuilder

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

pub fn workspace_process(&self) -> ProcessBuilder

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

pub fn process_no_wrapper(&self) -> ProcessBuilder

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

Trait Implementations

impl Debug for Rustc

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

Formats the value using the given formatter.
