Implementations

impl Command

pub fn new<T>(module_path: T) -> Command

where T: AsRef<OsStr>,

Constructs a new Command for launching the executable at path module_path with no arguments and no environment by default. Builder methods are provided to change these defaults and otherwise configure the process.

pub fn me() -> Result<Command>

Constructs a new Command for launching the current executable.

pub fn arg<'a, T>(&'a mut self, arg: T) -> &'a mut Command

where T: AsRef<OsStr>,

Adds an argument to pass to the program.

pub fn args<'a, T>(&'a mut self, args: &[T]) -> &'a mut Command

where T: AsRef<OsStr>,

Adds multiple arguments to pass to the program.

pub fn env<'a, T, U>(&'a mut self, key: T, val: U) -> &'a mut Command

where T: AsRef<OsStr>, U: AsRef<OsStr>,

Inserts or updates an environment variable mapping.

pub fn spawn(&self) -> Result<Process>

Executes the command as a child process, which is returned.
