Module error 

Custom error types for the NTP server. Custom error types for the NTP server.

All public APIs continue to return io::Result<T> for backward compatibility. Internally, errors are constructed as NtpServerError variants and converted to io::Error automatically via From<NtpServerError> for io::Error.

Users who want programmatic error matching can downcast via io::Error::get_ref():

use ntp_server::error::NtpServerError;

match result {
    Ok(()) => println!("server running"),
    Err(e) => {
        if let Some(srv_err) = e.get_ref()
            .and_then(|inner| inner.downcast_ref::<NtpServerError>())
        {
            match srv_err {
                NtpServerError::Protocol(p) => eprintln!("protocol error: {p}"),
                NtpServerError::Nts(n) => eprintln!("NTS error: {n}"),
                _ => eprintln!("server error: {srv_err}"),
            }
        }
    }
}
