How to customize multiple TLS versions？

[dslchd]

Hello everyone, I want the server to support TLS 1.2, TLS 1.3 at the same time, which API should I use, or what method should I use to make the service support multiple versions of TLS at the same time?

I didn't find any workaround from the example.

Could you enable Rustls tls12 and see if that solves your problem?

Maybe we should consider enabling this by default as well (rustls does it) with tls-rustls.
EDIT: Indeed, #130 addresses this.
