proto: Use the channel codec channel type

2026-01-22T16:16:44Z

Remove the channel type from Unverified and Verified channels and instead use the channel type in the underlying channel codec. The codec requires such type in order to restrict messages sets. Instead of duplicating it, this commit simply makes it that there is now only a single channel type attached to a channel structure. The resulting `struct Channel` in the end gets it copied from the channel codec as the framed_tls gets split and given to the `Reactor`. Down the line, we need a channel type attached to the `Channel` in order to know if it is a client or not and authenticated or not. Signed-off-by: David Goulet

proto: Make VerifiableChannel::check() async

2026-01-22T16:16:44Z

Relay initiator needs to send CERTS and AUTHENTICATE in that function after verifiying the channel. And thus require to be async. Signed-off-by: David Goulet

proto: Make CERTS cell optionnable for UnverifiedChannel

2026-01-22T16:16:44Z

This requires to make a series of cert and digest also optionnable in the VerifiedChannel. This change is needed because as a relay responder, you might get the CERTS or not depending on if the other side wants to authenticate. Client and bridges do not authenticate and thus it is expected to not have a CERTS cell. This leads to the UnverifiedChannel::check() function to return early with a VerifiedChannel without any identity attached to it. Signed-off-by: David Goulet

They are public but avoid anyone outside implementing them. Signed-off-by: David Goulet

proto: Add traits for public channel views

2026-01-13T18:46:18Z

Add traits that will be returned outside tor-proto allowing us to not expose client and relay specific channels. The goal is for the tor-chanmgr to get those objects implementing those traits and can build and run the reactor without knowing the specific underlying type. This allows us to have less code duplication and less client/relay distinction in the chanmgr. Signed-off-by: David Goulet

proto: Split VerifiedChannel::finish()

2025-11-19T19:42:47Z

Move the client specific code into VerifiedClientChannel as in sending the NETINFO cell. The rest is pretty much boiler plate to build a channel reactor. The relay finish() code is coming in a followup commit. Signed-off-by: David Goulet

proto: Use the new client specific channels

2025-11-19T19:42:47Z

By changing the connect() returned object we therefore officially make VerifiedChannel and UnverifiedChannel crate only objects. Thus, this commit changes visibility on most things. Signed-off-by: David Goulet
