`&` isn't a parameter annotation in Rust, it's two unary operators, two type annotations (general) and a pattern-matching operator.
The latter of which `ref` also is, incidentally, it means "capture a value by reference" in a pattern: https://play.rust-lang.org/?gist=30b436d83701f74b986aea978fa... (& meaning "capture a reference by its target" in that context, which is logically the structural inverse of the operator)
