So, apparently the chrome/geckodriver processes will terminate on their own if the user sends ctrl+c to the console. It will *not* terminate on its own if the program finishes running naturally.
If you're interested in terminating it on your own, like I also was, here is how I went about it.
```
use std::process::{Child, Command};
fn main() {
let mut s = Server::default();
s.start();
s.shutdown();
}
struct Server {
child: Option<Child>
}
impl Default for Server {
fn default() -> Self {
Self {
child: None
}
}
}
impl Server {
fn start(&mut self) {
self.child = Some(Command::new("./chromedriver")
.spawn()
.expect("ls command failed to start"));
}
fn shutdown(&mut self) {
input(None); // wait for input so you can observe the process
self.child.as_mut().unwrap().kill();
self.child.as_mut().unwrap().wait();
println!("shutdown");
}
}
pub fn input(prompt: Option<String>) {
let mut input = String::new();
match prompt {
Some(prompt) => println!("{}", prompt),
None => ()
}
io::stdin().read_line(&mut input).expect("Failed to read input");
}
```
