Struct TrigraphAnalyzer 

pub struct TrigraphAnalyzer;

TrigraphAnalyzer is an analyzer that calculates the strength of a password based on the frequency of trigraphs (sequences of three characters).

It works by counting the occurrences of each trigraph in the password and then calculating the entropy of these frequencies. Higher entropy indicates a more random and thus stronger password.

Examples

use password_strength::analyzer::trigraph::TrigraphAnalyzer;
use password_strength::analyzer::Analyzer;

let analyzer = TrigraphAnalyzer::default();

let password = "abcdef";
let score = analyzer.analyze(password);
assert!(score > 0.0);
assert!(score <= 1.0);

let password = "password123";
let score = analyzer.analyze(password);
assert!(score > 0.0);
assert!(score <= 1.0);

let password = "1234567890";
let score = analyzer.analyze(password);
assert!(score > 0.0);
assert!(score <= 1.0);

let password = "!@#$%^&*()";
let score = analyzer.analyze(password);
assert!(score > 0.0);
assert!(score <= 1.0);

let password = "ab";
let score = analyzer.analyze(password);
assert_eq!(score, 0.0);
