I'm doing some complex TLS certificate resolving logic and the fact that ResolvesServerCert trait takes ClientHello by value rather than by reference is a bit annoying. Since it also does not implement Clone and cannot be created (new is private to crate) I cannot pass it to more than one other implementer of ResolvesServerCert and that's sometimes needed.

I understand that it's minor issue and would break API, but maybe in some future versions it can be improved.

Thanks!

Describe the solution you'd like
Pass ClientHello by reference / make it Clone / wrap in Arc

Have you looked at the Acceptor API? It is quite a bit more powerful and could probably handle your use case.

@djc Yes, thanks, I know about it, but for me ResolvesServerCert is mostly enough. I solved my case by adding my own internal trait that takes ClientHello by ref, so at least for now it's not a problem.

Just an idea for future releases that it might make people's life a bit easier.

Thanks!
