sure if more work is needed for 0RTT. Untested.

That would have been broken before this with the mutually exclusive cbindgen features? Anyway, use the full feature

Wdym full feature?

are you trying to ship main in nix or the latest release? the latest release does not include this http3 feature

for features, that would be like cargo --features=full or similar.
