NAME

       "Object::Pad::ClassAttr::Struct" - declare an "Object::Pad" class to be struct-like

SYNOPSIS

          use Object::Pad;
          use Object::Pad::ClassAttr::Struct;

          class Colour :Struct {
             # These get :param :mutator automatically
             has $red   = 0;
             has $green = 0;
             has $blue  = 0;

             # Additional methods are still permitted
             method lightness {
                return ($red + $green + $blue) / 3;
             }
          }

          my $cyan = Colour->new( green => 1, blue => 1 );

DESCRIPTION

       This module provides a third-party class attribute for Object::Pad-based classes, which
       applies some attributes automatically to every field added to the class, as a convenient
       shortcut for making structure-like classes.

CLASS ATTRIBUTES

   :Struct
          class Name :Struct ... { ... }

       Automatically applies the ":param" and ":mutator" attributes to every field defined on the
       class, meaning the constructor will accept parameters for each field to initialise the
       value, and each field will have an lvalue mutator method.

       In addition, the class itself gains the ":strict(params)" attribute, meaning the
       constructor will check parameter names and throw an exception for unrecognised names.
