Is it possible to see the validation state(whether true or false) of a specific set_rules?

Lets say I have:

Code:

$this->form_validation->set_rules('username', 'Username', 'required');

Is it possible to see the validation state(whether true or false) of a specific set_rules?

no error if empty string using form_helper

Code:

if (form_error('username') == '')
{
   // ....
}

[quote author="osci" date="1305545326"]no error if empty string using form_helper

Code:

if (form_error('username') == '')
{
   // ....
}

[/quote]

Thank you for your example.

This also works well:

Code:

$field_required = $this->form_validation->required($str);

Code:

function field_check($value, $str)
        {
            $field_required = $this->form_validation->required($str);
            
            $field = array();
                
            if($field_required == 1)
            {
                        }
                }

I overlooked this example in the user guide:

Code:

if ($this->form_validation->run('signup') == FALSE)
