how to add custom username available and email available methods as rules in kohana

What is the correct format to add rules to check unique username and email in kohana 3.3

I have tried the followings

 array(array($this, 'unique'), array('username', ':value')); // added similar to email also
 array('username',array('unique_username'); // / added similar to email also
 array('username',array('unique_username',array(':value')); // / added similar to email also

public static function unique_username($username)
{
    echo 'running';

    // Check if the username already exists in the database
    return ! DB::select(array(DB::expr('COUNT(username)'), 'total'))
        ->from('users')
        ->where('username', '=', $username)
        ->execute()
        ->get('total');
}

I am getting the following error

Argument 3 passed to Kohana_Validation::rule() must be an array, string given

I can't give you an exact answer because you don't show your class name. For example, if your class was named Model_User here's how your would use a static method as a validation callback:

->rule('username', 'Model_User::unique_username', array(':value'));

or

->rule('username', array('Model_User', 'unique_username'), array(':value'));
