TLS 1.3 0-RTT support

[digitwolf]

Hi all,

I couldn't find an API to enable 0-RTT.
Is there an easy way to use this lib and enable it?

For the client or the server? For the client, have a look at https://docs.rs/rustls/latest/rustls/struct.ClientConnection.html#method.early_data. For the server, that's only recently been implemented on the main branch.

@djc thank you! I need both.
When do you think it will make to a release?

[digitwolf]

@djc But how do I use ClientConnection in hyper? I thought that the idea of this crate is to hide rustls from hyper.
It looks like it is an internal rustls API that is not exposed to hyper.

It would be nice if the HttpsConnector would automatically write to early data

I'm not sure what it would take to bring early data support to hyper, but it's definitely an interesting project!
