That's just your lack of familiarity with the foreign-to-you language (you may be unable to read Korean too, despite Korean being pretty readable).
Syntactically, Rust is pretty unambiguous, especially compared to C-style function and variable definitions. You get fn and let keywords, and definitions that are generally read left-to-right, instead of starting with an arbitrary identifier that may be a typedef, a preprocessor macro, or part of a type that is read in so-called "spiral" order (which isn't even a spiral, but more complex than than).
