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.
