Struct LocalNetworkNumber 

pub struct LocalNetworkNumber(/* private fields */);

The number of the network a single-port node is attached to, shared between the task that owns its Number controls and the senders that read it. Each NetworkLayer holds one (NetworkLayer::local_network_number), and clones share one value. Reading or publishing takes no lock.

It starts unknown. The layer never learns a number by itself: the owner of its Number controls publishes the state it holds whenever an announcement may have changed it, and a registered Network Port’s owner also publishes the port’s number at startup. The value is a copy of that state, never a second authority.

Implementations

impl LocalNetworkNumber

pub fn publish(&self, state: NetworkNumber)

Record the number state holds. An unknown state records unknown; a known number is always in 1..=65534.

pub fn get(&self) -> Option<u16>

The last number published, or None while it is unknown.
