Struct PatternAnalyzer 

pub struct PatternAnalyzer { /* private fields */ }

PatternAnalyzer analyzes passwords for common weak patterns.

It checks for:

• Keyboard patterns (e.g., “qwerty”, “asdf”).
• Repeated characters (consecutive like “aaa” or high frequency like “banana”).
• Sequential characters (e.g., “abc”, “123”).
• Common character substitutions (e.g., “@” for “a”, “3” for “e”).
• Repeated sequences (e.g., “abcabc”, “passpass”).

Penalties are applied for each detected weakness, reducing the overall score from 1.0.

Examples

use password_strength::analyzer::{Analyzer, pattern::PatternAnalyzer};

let analyzer = PatternAnalyzer::default();
println!("Score for 'qwerty12345': {}", analyzer.analyze("qwerty12345"));
println!("Score for 'P@sswOrd!': {}", analyzer.analyze("P@sswOrd!"));

Trait Implementations

impl Analyzer for PatternAnalyzer

fn analyze(&self, password: &str) -> f32

Analyzes the password strength based on detected patterns. Returns a score between 0.0 (weakest) and 1.0 (strongest relative to patterns).

impl Clone for PatternAnalyzer

fn clone(&self) -> PatternAnalyzer

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PatternAnalyzer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PatternAnalyzer

fn default() -> Self

Returns the “default value” for a type.
