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: lib.rs
    path of file: ./repos/pglowrpg/libs/lib_text_ops/src
    
    the code of the file until where you have to start completion: pub mod game_str;
pub mod input;
pub mod menu_str
    
pub fn input_flag_error(st: String) {
	println!(
		"ERROR, wrong flag used in macro invocation for input: \n{}\n",
		st
	);
	println!("Should be either opt or num (or you forgot the wordlist).");
}
