How to send close notify in the native-tls?

help
1

I found this method for rustls crate:

but can't for native-tls
maybe, I forgot about some feature just? without sending this signal, my client application warns me about TLS connection closed unexpectedly

Thanks for any ideas!

You are probably looking for shutdown().

Thank you much, I've tried it before but maybe called this method on the wrong step.
In my recent app implementation it's finally work!

Just should I execute it before flush method or after?

If OpenSSL has a sane API design for this I would expect shutdown to implicitly call flush, but I don't know if OpenSSL actually does that, so just to be safe you can call flush before shutdown.
