Trait cage::command_runner::Command[−][src]

pub trait Command {
    fn arg<S: AsRef<OsStr>>(&mut self, arg: S) -> &mut Self;

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

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

    fn status(&mut self) -> Result<ExitStatus>;

    fn command_failed_error(&self) -> ErrorKind;

    fn args<S: AsRef<OsStr>>(&mut self, args: &[S]) -> &mut Self { ... }

    fn exec(&mut self) -> Result<()> { ... }
}

A stripped down interface based on std::process::Command. We use this so we can mock out shell commands during tests.

Required methods

fn arg<S: AsRef<OsStr>>(&mut self, arg: S) -> &mut Self[src]

Add an arugment to our command.

fn env<K, V>(&mut self, key: K, val: V) -> &mut Self where
    K: AsRef<OsStr>,
    V: AsRef<OsStr>, [src]

Set an environment variable for the process we’re about to run.

fn current_dir<P: AsRef<Path>>(&mut self, dir: P) -> &mut Self[src]

Set the current working directory for the child process we’ll create.

fn status(&mut self) -> Result<ExitStatus>[src]

Run our command.

fn command_failed_error(&self) -> ErrorKind[src]

Make an error representing a failure of this command.

Provided methods

fn args<S: AsRef<OsStr>>(&mut self, args: &[S]) -> &mut Self[src]

Add several arguments to our command.

fn exec(&mut self) -> Result<()>[src]

Run our command as per status, returning an error if the command fails.
