# String tools `strtools` is a collection of string related utilities, not provided by standart library. Especially useful when your project deals with lot of manipulations around `String` or `&str` Pads a string with zeros, resulted string would be in length given in second argument # Examples ```rust let str = String::from("9"); let padded_string = strtools::pad(str, 3); assert_eq!(padded_string, "009"); ``` --- # Panics When length of given string is bigger than the wanted to be length, program panics: ```rust #[should_panic] fn can_panic() { let str = String::from("98798"); strtools::pad(str, 3); } ```
