How to check if a string contains only letters and numbers using RegEx in Rust

Answer 1

use regex::Regex;

fn is_alphanumeric(s: &str) -> bool {
    // Define the regular expression for alphanumeric characters
    let alphanumeric_regex = Regex::new(r"^[a-zA-Z0-9]+$").unwrap();

    // Use is_match to check if the string matches the pattern
    alphanumeric_regex.is_match(s)
}

fn main() {
    let s = "VuZ3q7J4wo35Pi";

    if is_alphanumeric(s) {
        println!("The string contains only letters and numbers.");
    } else {
        println!("The string contains characters other than letters and numbers.");
    }
}


      
/*
run:

The string contains only letters and numbers.
     
*/
