It is, but I think people accept that these are automatically generated outputs from compiler-created code.

Like any notation, once you understand how to break it apart and you learn what symbols mean, it becomes easier to interpret large fragments like this.

One pretty significant issue for newcomers is that rustdoc emphasises traits, rather than methods. Sometimes there is more indirections. It takes more insider knowledge to know that fmt() is actually called by the println!() macro, so you're unlikely to encounter that method unless you're digging into the internals.
