None is a valid email?

[kpartal1]

use validator::ValidateEmail;

fn main() {
    let email: Option<String> = None;
    println!("{}", email.validate_email());
}

This code prints true. Is this intentional?

By default, None values are returning true because you're meant to put whether the option is required or not in the macro, eg

    #[validate(required, email)]
    email: Option<String>,

If it was returning false, if you had:

    #[validate(email)]
    email: Option<String>,

You would need to add an option to skip the field is Null
