How to validate a 10-digit phone number with hyphens (e.g. 333-555-1234) using RegEx in Rust

Answer 1

use regex::Regex;

fn main() {
    let phone_number = "333-555-1234";
    let pattern = Regex::new(r"^\d{3}-\d{3}-\d{4}$").unwrap();

    if pattern.is_match(phone_number) {
        println!("Valid phone number format");
    } else {
        println!("Invalid phone number format");
    }

    // Example with invalid number
    let invalid_number = "333-555-12345";
    if pattern.is_match(invalid_number) {
        println!("Valid phone number format");
    } else {
        println!("Invalid phone number format");
    }
}


     
/*
run:
  
Valid phone number format
Invalid phone number format
    
*/
