cmd: Command

Implementations

impl Clang

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

where K: AsRef<OsStr>, V: AsRef<OsStr>,

Specify an environment variable.

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

where K: AsRef<OsStr>,

Remove an environmental variable.

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.

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.

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.

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.

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.

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.

pub fn run(&mut self) -> CompletedProcess

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

pub fn run_fail(&mut self) -> CompletedProcess

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

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.

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

Set the path where the command will be run.

impl Clang

pub fn new() -> Self

Construct a new clang invocation. clang is not always available for all targets.

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

Provide an input file.

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

Specify the name of the executable. The executable will be placed under the current directory and the extension will be determined by bin_name.

pub fn target(&mut self, target_triple: &str) -> &mut Self

Specify which target triple clang should target.

pub fn no_stdlib(&mut self) -> &mut Self

Pass -nostdlib to disable linking the C standard library.

pub fn arch(&mut self, arch: &str) -> &mut Self

Specify architecture.

pub fn lto(&mut self, lto: &str) -> &mut Self

Specify LTO settings.

pub fn use_ld(&mut self, ld: &str) -> &mut Self

Specify which ld to use.

Trait Implementations

impl Debug for Clang

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

Formats the value using the given formatter.

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.
