rustHow to match a URL with a regex in Rust?
Matching a URL with a regex in Rust is a simple process. The following example code block shows how to do this:
let re = Regex::new(r"^(https?://)?([\da-z\.-]+)\.([a-z\.]{2,6})([\/\w \.-]*)*\/?$").unwrap();
let url = "https://www.example.com/path/to/page";
if re.is_match(url) {
println!("URL matches the regex!");
}
The output of the example code is:
URL matches the regex!
