tracing-tree
Instrument your application with tracing
and get tree-structured summaries of your application activity with timing
information on the console:

Setup
After instrumenting your app with
tracing, add this subscriber like this:
let subscriber = Registry::default().with(HierarchicalLayer::new(2));
tracing::subscriber::set_global_default(subscriber).unwrap();
