SslStream does not implement clone about rust-openssl HOT 7 CLOSED

This will probably be necessary for implementing high-performance HTTP/2.0.

from rust-openssl.

Doing this properly will be a bit tricky since OpenSSL doesn't expose the ability to bump an SSL struct's refcount manually. I guess I could wrap it in an Arc but that's a bit sad.

I also just ran into this. I clone the TcpStreams to make a Request and Response that a handler can deal with, and found I can't do so if I use SslStreams instead.

Ya, in Hyper we have to wrap the SslStream in Arc<Mutex>, which is far from ideal. We could bug the OpenSSL guys to add that API.

An Arc<Mutex> wrapper means that writing and reading cannot be done in parallel. It would really have to be implemented at the level of this library in order to allow for parallel reading and writing.

👍 I need this enhancement for the reasons stated by @retep998.

Thanks! I'm excited for this change to be up on crates.io.
