Struct Bound 

pub struct Bound { /* private fields */ }

A listener already bound, the address it holds, and the face its judgement gave it.

The face travels with the listener because it is the verdict about this very address: a face carried apart from its listener could be served on a socket it was never judged for. The address is read once, at bind, because a city asked to serve on :0 holds a port only the listener knows (wire D16).

Implementations

impl Bound

pub fn local_addr(&self) -> SocketAddr

The address the listener holds: the port the operating system gave when bind was asked for port 0, the one asked for otherwise. Every reader that hands the city’s address on reads this one, never the address bind was given.
