It doesn't currently seem possible as of 0.7.2 to bind a Server to a Unix socket (identifed by a std::os::unix::net::SocketAddr), however it's useful to be able to host a service behind a reverse proxy on a unix socket to avoid "polluting" local TCP ports.

It seems like the topic of Unix sockets has been mentioned in #66 before, but I unfortunately cannot find the APIs referred to in the issue description (I also checked older versions, found nothing).
