Function vboxhelper::wait_for_croak

pub fn wait_for_croak(
    vid: &VmId, 
    timeout: Option<(Duration, TimeoutAction)>
) -> Result<(), Error>

Wait for a virtual machine to self-terminate.

The caller can choose to pass a timeout and what action should be taken if the operation times out. If the timeout occurs the caller can choose whether to return a timeout error or kill the virtual machine.

use std::time::Duration;
use vboxhelper::{TimeoutAction, wait_for_croak, VmId};
fn impatient() {
  let twenty_seconds = Duration::new(20, 0);
  let vmid = VmId::from("myvm");
  wait_for_croak(&vmid, Some((twenty_seconds, TimeoutAction::Kill)));
}

This function polls is_vm_state() which calls get_vm_info(). A very sad state of affairs. :(
