fn main() {
    // Instead of exiting a critical service state, we exit with a service state of "unknown" on error.
    Runner::new()
        .on_error(|e| (ServiceState::Unknown, e))

// This example uses anyhow
fn do_check() -> Result<Resource, anyhow::Error> {
    // Do something which returns an error.
