Is it a new style? It seems inconsistent within itself... for example sometimes the code starts one a new line after the opening brace, sometimes it starts on the same line, sometimes the closing brace is on the same line sometimes it's not. I don't know enough of Rust to know whether this means anything or the coder is just being sloppy.
