Declare::Constraints::Simple::Result - Validation Result

  my $result = $constraint->($value);
  my $message = $result->message;
  my $path    = $result->path;

This represents a result returned by a Declare::Constraints::Simple constraint. Objects of this kind overload their boolean context, so the value of the is_valid() accessor is reflected to it.

new()

Constructor. As you will mostly just receive result objects, you should never be required to call this yourself.

Sets the results validity flag.

is_valid()

Boolean accessor telling if this is a true result or not.

The error message. Useful only on non-valid results.

message()

Returns the message of the result object.

This adds another level at the beginning (!) of the results constraint stack. This is mostly intended to use for the "prepare_generator"method in Declare::Constraints::Simple::Library package.

Returns a string containing the stack() contents joined together by the $separator string (defaulting to ".").

stack()

Returns an array reference containing the results currrent stack. This is a list of the constraints path parts. This is usually just the constraints name. If there's additional info, it is appended to the name like "[$info]".
