Abstraction of command methods in multiple libraries.

Required Methods

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

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

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.

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

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

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

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

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

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

fn spawn(&mut self) -> AnyResult<Child>

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

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
