Struct Command 

pub struct Command(Command);

A wrapper around the command API of the underlying async runtime.

Unlike the socket transports, unixexec isn’t run-time selected: async-process is used whenever it’s compiled in (its pipes are Async<_>, which any runtime can drive), so with both backends a tokio app connecting over unixexec: picks up async-io’s reactor.

Implementations

impl Command

pub fn new<S>(program: S) -> Self

where S: AsRef<OsStr>,

Constructs a new Command for launching the program at path program.

pub fn for_unixexec(unixexec: &Unixexec) -> Self

Constructs a new Command from a unixexec address.

pub fn arg0<S>(&mut self, arg: S) -> &mut Self

where S: AsRef<OsStr>,

Sets executable argument.

Set the first process argument, argv[0], to something other than the default executable path.

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

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

Adds multiple arguments to pass to the program.

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

Executes the command as a child process, waiting for it to finish and collecting all of its output.

pub fn stdin<T: Into<Stdio>>(&mut self, cfg: T) -> &mut Self

Sets configuration for the child process’s standard input (stdin) handle.

pub fn stdout<T: Into<Stdio>>(&mut self, cfg: T) -> &mut Self

Sets configuration for the child process’s standard output (stdout) handle.

pub fn stderr<T: Into<Stdio>>(&mut self, cfg: T) -> &mut Self

Sets configuration for the child process’s standard error (stderr) handle.

pub fn spawn(&mut self) -> Result<Child, Error>

Executes the command as a child process, returning a handle to it.
