fn bind_addrs(
addrs: &[SocketAddr],
listening: &mut Vec<SocketAddr>,
defaulted: bool,
) -> Result<Vec<TcpListener>>Expand description
Binds the addresses nothing answers for yet, extending listening as it
goes so a wildcard entry covers the ones behind it.
Failures surface here, before any listener is served. A defaulted address is skipped instead, since the built-in pair only guesses which loopback families the host has.
