Struct RandomPasswordEntropy 

pub struct RandomPasswordEntropy { /* private fields */ }

Entropy bits estimate defined in NIST SP-800-63-1 Randomly Selected Passwords. see http://csrc.nist.gov/publications/nistpubs/800-63-1/SP-800-63-1.pdf A1. “Randomly Selected Passwords”

Example

   use passay_rs::entropy::RandomPasswordEntropy;
   use passay_rs::rule::Rule;
   use passay_rs::rule::character_characteristics::CharacterCharacteristics;
   use passay_rs::rule::character::CharacterRule;
   use passay_rs::rule::character_data::EnglishCharacterData;
   use passay_rs::rule::allowed_character::AllowedCharacter;
   use passay_rs::rule::PasswordData;
   use passay_rs::entropy::Entropy;

   let allowed_rules = AllowedCharacter::from_chars("abcdefghijklmnopqrstuvwxyzL");
   let ch_rules = vec![
       CharacterRule::new(Box::new(EnglishCharacterData::UpperCase), 1).unwrap(),
       CharacterRule::new(Box::new(EnglishCharacterData::LowerCase), 1).unwrap(),
   ];
   let char_rule = CharacterCharacteristics::with_rules_and_characteristics(ch_rules, 2).unwrap();

   let rules:Vec<Box<dyn Rule>> = vec![Box::new(allowed_rules), Box::new(char_rule)];
   let entropy = RandomPasswordEntropy::new(rules.as_slice(), &PasswordData::with_password("heLlo".to_string())).unwrap();
   let ent = entropy.estimate();
   assert_eq!(28.50219859070546, ent);
