pub fn loopback(port: u16) -> SocketAddrExpand description
The bind address. Loopback only, and not configurable.
This process reads the operator’s filesystem and answers questions about it. Binding it
to anything routable turns a local tool into an unauthenticated file-disclosure service
on the network, and the one thing that reliably happens to a --bind flag is that
somebody sets it to 0.0.0.0 to reach it from another machine. The port is
configurable; the interface is not.
