I think we would need to do #603 before this is possible, but I agree this would be a good clarity and efficiency improvement.

Note #998 achieves this another (much less graceful) way. This PR can remain for doing it in the more reasonable way: so please add a `git revert 5288fcf` to the...

Could you write precise reproduction steps for this? And preferably a pcap of it happening with a matching SSLKEYLOG?

Maybe worth noting that (AFAICT) nobody else follows this guidance either: - NSS: [SSL_ExportKeyingMaterial](https://github.com/servo/nss/blob/master/lib/ssl/ssl.h#L835) - BoringSSL: [SSL_export_keying_material](https://boringssl.googlesource.com/boringssl/+/27a0d086f7bbf7076270dbeee5e65552eb2eab3a/include/openssl/ssl.h#1300) - OpenSSL: [SSL_export_keying_material](https://www.openssl.org/docs/man1.1.1/man3/SSL_export_keying_material.html) - Microsoft CapiNG: [SslExportKeyingMaterial](https://docs.microsoft.com/en-us/windows/win32/seccng/sslexportkeyingmaterial) - golang crypto/tls: [ConnectionState.ExportKeyingMaterial](https://pkg.go.dev/crypto/tls#ConnectionState.ExportKeyingMaterial) Not that...

No plans at the minute. I know it's used for some VPNs, webrtc and some iot things. What is your use case?

Looking good! 👍

DTLS/TLSMessage sounds ok, but beware that some performance relies on Message being moved by value into the processing functions: so the traits will need to cover these cases by exposing...

I don't have any wip branch for that yet. But I'll push one once I do and link it here.

How about separate `DatagramClientSession`/`DatagramServerSession` types? I'm assuming these types need some kind of extra methods for timed triggering of retransmits? On the question of `ClientSessionImpl`, could we inject implementations of...
