Module statistics

Statistics services.

It includes:

• A factory function to build the structs needed to collect the tracker metrics.
• A get_metrics service to get the tracker metrics.

Tracker metrics are collected using a Publisher-Subscribe pattern.

The factory function builds two structs:

• An statistics EventSender
• An statistics Repo

let (stats_event_sender, stats_repository) = factory(tracker_usage_statistics);

The statistics repository is responsible for storing the metrics in memory. The statistics event sender allows sending events related to metrics. There is an event listener that is receiving all the events and processing them with an event handler. Then, the event handler updates the metrics depending on the received event.

For example, if you send the event Event::Udp4Connect:

let result = event_sender.send_event(Event::Udp4Connect).await;

Eventually the counter for UDP connections from IPv4 peers will be increased.

pub struct Metrics {
    // ...
    pub udp4_connections_handled: u64,  // This will be incremented
    // ...
}
