Struct Command

pub struct Command { /* private fields */ }

A command wrapper that simplifies interaction with external commands.

Implementations

impl Command

pub fn new(name: impl Into<PathBuf>) -> Command

Construct a new command wrapper.

pub fn arg<A>(&mut self, arg: A)

where A: AsRef<OsStr>,

Push an argument to the command.

pub fn args<I>(&mut self, args: I)

where I: IntoIterator, I::Item: AsRef<OsStr>,

Push a collection of arguments to the command.

pub fn working_directory(&mut self, path: impl AsRef<Path>)

Configure the working directory of this command.

pub fn run_lines(self) -> Result<Vec<String>, Error>

Run the given command, return all lines printed to stdout on success.

pub fn run_stdout(self) -> Result<String, Error>

Run the given command, return a string of all output.

pub fn run_checked(self) -> Result<(), Error>

Run the given command, only checking for status code and providing diagnostics.

pub fn run_inherited(&self) -> Result<(), Error>

Run the given command, inheriting stdout, stderr from the current process.

This is discouraged, since it basically requires the command to be running on the main thread.

pub fn run(self) -> Result<Output>

Run the given command, return a string of all output.

pub fn status(self) -> Result<ExitStatus>

Run the command and wait for exit status.
