Struct PasswordField 

pub struct PasswordField {
    pub name: String,
    pub required: bool,
    pub error_messages: HashMap<String, String>,
    pub widget: Widget,
    pub help_text: String,
    pub initial: Option<Value>,
    pub min_length: usize,
    pub require_uppercase: bool,

}

A field for password validation with strength requirements

Validates password strength including minimum length, required character types.

Examples

use reinhardt_forms::fields::PasswordField;
use reinhardt_forms::Field;
use serde_json::json;

let field = PasswordField::new("password")
    .min_length(8)
    .require_uppercase(true)
    .require_digit(true);

// Valid strong password
let result = field.clean(Some(&json!("SecurePass123")));
assert!(result.is_ok());

// Invalid: too short
let result = field.clean(Some(&json!("Pass1")));
assert!(result.is_err());
