> Tor

you are using a Tor daemon in it. tor has a rust implementation and when used with rust has stream objects etc.

an example of how it's used can be found in https://gitlab.torproject.org/tpo/core/oniux

Yes, I wrote the current tor transport as a quick demo/testground for custom transports.

Arguably directly embedding the rust tor implementation would be more useful for the typical iroh user that wants an embeddable library. I just did not get to it yet.

But thanks for the link.
