arc::Context::node_count
========================

Synopsis
--------

.. code-block:: rust
   
   pub fn node_count(&self) -> u32;

Return the number of nodes connected to your LinQ Network context. Any time you connect to a remote linq_network instance, the node count will increase by 1. Anytime you close a connection to a remote linq_network instance, the node count will decrease by 1.

Parameters
----------

None.

Examples
--------

.. rubric:: Example keeping track of how many nodes your application is connected to.

.. code-block:: rust

   let net = linq_network::arc::Context::new();

   assert!(net.node_count(netw) == 0);

   linq_network_socket tcp = net.connect(linq_network::Endpoint::Tcp(33455));
   
   assert!(net.node_count(netw) == 1);

   linq_network_socket ipc = net.connect(linq_network::Endpoint::Ipc("/local"));

   assert!(net.node_count(netw) == 2);

   linq_network_close(netw, ipc);

   assert!(net.node_count(netw) == 1);

   linq_network_close(netw, tcp);

   assert!(net.node_count(netw) == 0);
