Validator::Custom::Rule - Rule object

  use Validator::Custom;
  my $vc = Validator::Custom->new;
  
  # Create rule object
  my $rule = $vc->create_rule;
  $rule->require('id')->check(
    'ascii'
  );
  $rule->optional('name')->check(
   'not_blank'
  );
  
  # Validate
  my $data = {id => '001', name => 'kimoto'};
  my $result = $vc->validate($data, $rule);
  
  # Option
  $rule->require('id')->default(4)->copy(0)->message('Error')->check(
    'not_blank'
  );
