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: default_types.rs
    path of file: ./repos/ripgrep/crates/ignore/src
    
    the code of the file until where you have to start completion: /// This list represents the default file types that ripgrep ships with. In
/// general, any file format is fair 
    
    fn default_types_are_sorted() {
        let mut names = DEFAULT_TYPES.iter().map(|(aliases, _)| aliases[0]);
        let Some(mut previous_name) = names.next() else {
            return;
        };
        for name in names {
            assert!(
                name > previous_name,
                r#""{}" should be sorted before "{}" in `DEFAULT_TYPES`"#,
                name,
                previous_name
            );
            previous_name = name;
        }
    }
