As discussed in Discord, it would be useful if Tonic could be used via transports other than TCP sockets - for example a Unix domain socket.

I was just about to open an issue for this. I'm currently using this working branch of hyperlocal to implement a custom Server that serves on Unix domain sockets in a personal project. Converting the client Endpoint, however, is comparatively less trivial.

I am on vacation right now but ill drop a hint at what I think the correct solution should be. We should provide a MakeConnection builder option for both server and client. This MakeConnection should allow us to swap out the underlying asyncread/write.

Over at akshayknarayan@02defcd, I've written a temporary hack which addresses this issue in the same way as TLS support - a "unix" feature gate.

This relies on https://crates.io/crates/hyper-unix-connector, which is similar to hyperlocal except it also provides the plumbing needed to make this connector.

This approach probably should not be merged - in fact, @LucioFranco's suggestion of a MakeConnection builder would probably replace the current tls feature gate as well.

feat: make Endpoint connector swappable
9a27334 
Change the `connect()` API to lift up the use of `connector()` to
`Endpoint::connect()`, allowing users to provide their own
implementations (for example, Unix-domain sockets).
Any type which impls `tower_make::MakeConnection` is
suitable.

To avoid breaking the default case of HTTP(S), introduce
`connect_with_connector()` and retain `connect()`, which creates the
default connector according to the activated feature gate and passes it
to `connect_with_connector()`.

Fixes: hyperium#136

there's been a bit of churn on hyperlocal. see

what impact does this have on what you're proposing?

Changes in tonic to allow custom connectors in Endpoint are still necessary - the changes in hyperlocal would have impact on callers passing in custom connectors, but not directly here.

Hey just to update I'd like to get this in tonic for 0.1.
