pub fn spawn(
exe: &Path,
args: &[String],
env: &HashMap<String, String>,
cwd: &Path,
) -> Result<Child>Expand description
Spawn the child in its own process group (Unix) with given env/cwd/args.
kill_on_drop(true) is a belt-and-suspenders guard so an accidentally-dropped
Child never leaks a process (C-1 defense in depth).
