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: rule_normalize.rs
    path of file: ./repos/szyszka/src/rule
    
    the code of the file until where you have to start completion: use crate::rule::rules::*;

pub fn rule_normalize(data_to_change: &str, rule: &SingleRule) -> String {
    let return_string;

    match rule.rule_type {
        RuleType::Normalize
    
pub fn rule_normalize(data_to_change: &str, rule: &SingleRule) -> String {
    let return_string;

    match rule.rule_type {
        RuleType::Normalize => match rule.rule_place {
            RulePlace::ExtensionAndName => {
                return_string = slugmin::slugify_normal(data_to_change, !rule.rule_data.full_normalize);
            }
            _ => panic!("Invalid Rule Place for Normalization"),
        },
        _ => panic!("Invalid Rule Type for Normalization"),
    }

    return_string
}
