Implementations§

Source§

impl Rustc

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 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 Rustc
