Struct checked_command::CheckedCommand

pub struct CheckedCommand { /* fields omitted */ }

A wrapper around std::process::Command which hides the original status/output methods and replaces them with the versions from checked_command::CommandExt

Methods

impl CheckedCommand

fn as_std_command(&mut self) -> &mut Command

return a mutable reference to the wrapped std::process::Command this can be useful if the cammand has to be passed to a function or to access a extension trait for std::process::Command

fn into_std_command(self) -> Command

converts this Command into a std::process::Command (basically unwrapping it).

Note that this function was intentionally provided instead of Into<Command> as the main reason for this wrapper is to prevent forgetting to check the exit status. As such it will forward all calls except spawn,status and output which normally tend to be the last function ever called on a command instances. Therefore converting a CheckedCommand to a Command is quite likely a bug. (Through there are some cases where it makes sense).

fn new<S: AsRef<OsStr>>(program: S) -> CheckedCommand

creates a new CheckedCommand see std::process:Command::new for more details

fn arg<S: AsRef<OsStr>>(&mut self, arg: S) -> &mut CheckedCommand

calls std::process::Command::arg

fn args<I, S>(&mut self, args: I) -> &mut CheckedCommand where
    I: IntoIterator<Item = S>,
    S: AsRef<OsStr>, 

calls std::process::Command::args

fn env<K, V>(&mut self, key: K, val: V) -> &mut CheckedCommand where
    K: AsRef<OsStr>,
    V: AsRef<OsStr>, 

calls std::process::Command::env

fn env_remove<K: AsRef<OsStr>>(&mut self, key: K) -> &mut CheckedCommand

calls std::process::Command::env_remove

fn env_clear(&mut self) -> &mut CheckedCommand

calls std::process::Command::env_clear

fn current_dir<P: AsRef<Path>>(&mut self, dir: P) -> &mut CheckedCommand

calls std::process::Command::current_dir

fn stdin(&mut self, cfg: Stdio) -> &mut CheckedCommand

calls std::process::Command::stdin

fn stdout(&mut self, cfg: Stdio) -> &mut CheckedCommand

calls std::process::Command::stdout

fn stderr(&mut self, cfg: Stdio) -> &mut CheckedCommand

calls std::process::Command::stderr

fn spawn(&mut self) -> Result<CheckedChild, IoError>

calls std::process::Command::spawn and converts the Child into a CheckedChild

fn output(&mut self) -> Result<Output, Error>

calls CommandExt::checked_output on the wrapped Command

fn status(&mut self) -> Result<(), Error>

calls CommandExt::checked_status on the wrapped Command
