## Implementations§

Source§

### impl Cc

Source

#### pub fn into_raw_command(self) -> Command

In very rare circumstances, you may need a e.g. `bare_rustc()` or `bare_rustdoc()` with host runtime libs configured, but want the underlying raw `std::process::Command` (e.g. for manipulating pipes or whatever). This function will consume the command wrapper and extract the underlying `std::process::Command`.

Caution: this will mean that you can no longer use the convenience methods on the command wrapper. Use as a last resort.

Source

#### pub fn env<K, V>(&mut self, key: K, value: V) -> &mut Self
where K: AsRef<OsStr>, V: AsRef<OsStr>,

Specify an environment variable.

Source

#### pub fn env_remove<K>(&mut self, key: K) -> &mut Self
where K: AsRef<OsStr>,

Remove an environmental variable.

Source

#### pub fn arg<S>(&mut self, arg: S) -> &mut Self
where S: AsRef<OsStr>,

Generic command argument provider. Prefer specific helper methods if possible. Note that for some executables, arguments might be platform specific. For C/C++ compilers, arguments might be platform and compiler specific.

Source

#### pub fn args<V, S>(&mut self, args: V) -> &mut Self
where V: AsRef<[S]>, S: AsRef<OsStr>,

Generic command arguments provider. Prefer specific helper methods if possible. Note that for some executables, arguments might be platform specific. For C/C++ compilers, arguments might be platform and compiler specific.

Source

#### pub fn stdin<T: Into<Stdio>>(&mut self, cfg: T) -> &mut Self

Configuration for the child process’s standard input (stdin) handle.

See `std::process::Command::stdin`.

Source

#### pub fn stdout<T: Into<Stdio>>(&mut self, cfg: T) -> &mut Self

Configuration for the child process’s standard output (stdout) handle.

See `std::process::Command::stdout`.

Source

#### pub fn stderr<T: Into<Stdio>>(&mut self, cfg: T) -> &mut Self

Configuration for the child process’s standard error (stderr) handle.

See `std::process::Command::stderr`.

Source

#### pub fn inspect<I>(&mut self, inspector: I) -> &mut Self
where I: FnOnce(&Command),

Inspect what the underlying `Command` is up to the current construction.

Source

#### pub fn set_aux_fd<F: Into<OwnedFd>>( &mut self, new_fd: RawFd, fd: F, ) -> &mut Self

Set an auxiliary stream passed to the process, besides the stdio streams.

Source

#### pub fn run(&mut self) -> CompletedProcess

Run the constructed command and assert that it is successfully run.

Source

#### pub fn run_fail(&mut self) -> CompletedProcess

Run the constructed command and assert that it does not successfully run.

Source

#### pub fn run_unchecked(&mut self) -> CompletedProcess

Run the command but do not check its exit status. Only use if you explicitly don’t care about the exit status. Prefer to use `Self::run` and `Self::run_fail` whenever possible.

Source

#### pub fn current_dir<P: AsRef<Path>>(&mut self, path: P) -> &mut Self

Set the path where the command will be run.

Source§

### impl Cc

Source

#### pub fn new() -> Self

Construct a new platform-specific C compiler invocation.

WARNING: This means that what flags are accepted by the underlying C compile is platform- AND compiler-specific. Consult the relevant docs for `gcc`, `clang` and `mvsc`.

Source

#### pub fn new_cxx() -> Self

Construct a new platform-specific CXX compiler invocation. CXX_DEFAULT_FLAGS is passed from compiletest.

Source

#### pub fn input<P: AsRef<Path>>(&mut self, path: P) -> &mut Self

Specify path of the input file.

Source

#### pub fn library_search_path<P: AsRef<Path>>(&mut self, path: P) -> &mut Self

Adds directories to the list that the linker searches for libraries. Equivalent to `-L`.

Source

#### pub fn out_exe(&mut self, name: &str) -> &mut Self

Specify `-o` or `-Fe`/`-Fo` depending on platform/compiler.

Source

#### pub fn output<P: AsRef<Path>>(&mut self, path: P) -> &mut Self

Specify path of the output binary.

Source

#### pub fn optimize(&mut self) -> &mut Self

Optimize the output. Equivalent to `-O3` for GNU-compatible linkers or `-O2` for MSVC linkers.

## 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.
