// The link is updated to reference itself twice (as a source and a target):
link = links.Update(link, newSource: link, newTarget: link);

// Read operations:
Console.WriteLine($"The number of links in the data store is {links.Count()}.");
Console.WriteLine("Data store contents:");
var any = links.Constants.Any; // Means any link address or no restriction on link address
// Arguments of the query are interpreted as restrictions
var query = new Link<uint>(index: any, source: any, target: any);
links.Each((link) => {
    Console.WriteLine(links.Format(link));
    return links.Constants.Continue;
}, query);

// The link's content reset:
link = links.Update(link, newSource: default, newTarget: default);

// The link deletion:
links.Delete(link);
