You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: if2.rs
    path of file: ./repos/rust-course/assets/rustlings-zh/exercises/if
    
    the code of the file until where you have to start completion: // if2.rs

// 第一步：让我能够编译！
// 第二步：bar_for_fuz
    
pub fn fizz_if_foo(fizzish: &str) -> &str {
