pub async fn bind(
addr: SocketAddr,
key: Option<B3Hash>,
) -> Result<Bound, AxError>Expand description
Judges the bind face, then binds the listener.
ยงErrors
E_CONFIG_INVALID from decide_bind, without touching the
network, when no key is given; the same code
when the operating system refuses the address, most often because
another process holds the port, or cannot say which address it gave.
