Enum Delivery 

pub enum Delivery {
    Session,
    Advertisement,
    StatelessRpc,
}

Which part of a git conversation one call to the seam carries.

Why an SSH crate names an HTTP shape

This module is the seam, not the SSH transport: it is the join every front end plugs the protocol state machines into, and gunnar-http plugs into this one rather than growing a second copy of it. That is the whole reason the crate docs above call GitTransport “the seam” and not “the SSH bridge”.

The alternative was a second trait in gunnar-http with its own ServiceRequest, its own authorisation call and its own join to gunnar-wire — which is exactly the shape that produces two answers to “may this principal push”. Sharing one seam costs an enum with three variants and no dependencies; gunnar-http linking gunnar-ssh adds nothing to any build, because a gunnar server that speaks HTTP also speaks SSH and gunnar-ssh was already there.

If a build ever wants HTTP without SSH, this module and crate::server::Dispatch move to their own crate and nothing else changes. That build does not exist today, and inventing the crate for it now would be inventing a boundary before there is anything on both sides of it.

Variants

Session

One connection carries the advertisement, the negotiation and the pack. This is SSH, and it is what gunnar-wire’s Session::Connected means.

Advertisement

Smart HTTP GET /<path>/info/refs?service=…: write the advertisement and stop. Nothing is read from the client.

StatelessRpc

Smart HTTP POST /<path>/<service>: one stateless-rpc round.
