When we want to remove the ending substring or suffix of a string then the strip_suffix() method is required. With this method, the suffix specified (if matched) will be sliced out of the string. It returns the sliced suffix wrapped by Some. If the suffix is not matched or found, then a None is returned.
string.split_suffix()
string: This is the string whose suffix we want to remove.
suffix: This is the suffix of the string that we want to slice away.
fn main() {// create some stringslet str1 = "Edpresso";let str2 = "Educative";let str3 = "Rust";let str4 = "Educative is the best platform!";// strip some suffixesprintln!("Stripping {:?} from {} = {:?}","Ed",str1, str1.strip_suffix("Ed"));println!("Stripping {:?} from {} = {:?}","cative",str2, str2.strip_suffix("cative"));println!("Stripping {:?} from {} = {:?}","R",str3, str3.strip_suffix("R"));println!("Stripping {:?} from {} = {:?}","platform!",str4, str4.strip_suffix("platform!"));}
strip_suffix() method to remove the suffixes from the strings. Then we print the results to the console.
