pub struct Rustc {
    pub path: PathBuf,
    pub wrapper: Option<PathBuf>,
    pub verbose_version: String,
    pub host: String,
    // some fields omitted
}

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.

verbose_version: String

Verbose version information (the output of rustc -vV)

host: String

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

Methods

impl Rustc

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

Run 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

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

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