struct AppState {
  command: Mutext<Option<Child>>
}

fn start_command(state: State<'_, AppState) {
  let command = Command::new('binary path').args(args).spawn();
  *state.command.lock().unwrap() = Some(command);
}

fn stop_command(state: State<'_, AppState) {
  state
        .command
        .lock()
        .unwrap()
        .as_ref()
        .expect("child")
        .stdin
        .as_ref()
        .unwrap()
        .write("q".as_bytes());
}

Need to store a command child in state so that I can write to it later to tell the command to stop. I feel like this is a close as I've gotten to a correct solution but with the code like this the command starts correctly but when trying to stop it stdin is returning an Option<none> and then failing when I try to unwrap it and I really am at a loss as to why

Does it help if you add .stdin(Stdio::piped()) to the Command::new stuff?
