Example

fn main() { // Create a process for reading stdout let mut child = Command::new("sh").arg("-c").arg("sleep 1; echo aaa").spawn().unwrap();

// Create ProcReader from pid
let pid = Pid::from_raw(child.id() as i32);
let mut reader = ProcReader::from_stdout(pid);

// Wait the end of process
thread::sleep(Duration::from_secs(2));

// Read from ProcReader
let mut line = String::new();
let _ = reader.read_to_string(&mut line);
assert_eq!( "aaa\n", line);

} ```
