ah very sorry, I can see how this isn't all that clear. In the comment you've mentioned when I say "custom protocol" I mean a custom QUIC ALPNs:
https://datatracker.ietf.org/doc/html/rfc7301When we talk to mainline it's for discovery, which is separate from iroh connections, which always uses QUIC. Specifically: our fork of quinn, an implementation of QUIC in rust. Iroh is tightly coupled to quinn, and isn't swappable. Getting no_std support for us basically boils down to "can we get quinn to support no_std?". For that, see: https://github.com/quinn-rs/quinn/issues/579
