Module sc_network::service

Main entry point of the sc-network crate.

There are two main structs in this module: NetworkWorker and NetworkService. The NetworkWorker is the network. Network is driven by NetworkWorker::run future that terminates only when all instances of the control handles NetworkService were dropped. The NetworkService is merely a shared version of the NetworkWorker. You can obtain an Arc<NetworkService> by calling NetworkWorker::service.

The methods of the NetworkService are implemented by sending a message over a channel, which is then processed by NetworkWorker::next_action.
