Role::HasPayload::Auto - a thing that automatically computes its payload based on attributes

VERSION

version 0.007

SYNOPSIS

  package Example;
  use Moose;

  with qw(Role::HasPayload::Auto);

  sub Payload { 'Role::HasPayload::Meta::Attribute::Payload' }

  has height => (
    is => 'ro',
    traits   => [ Payload ],
  );

  has width => (
    is => 'ro',
    traits   => [ Payload ],
  );

  has color => (
    is => 'ro',
  );

...then...

  my $example = Example->new({
    height => 10,
    width  => 20,
    color  => 'blue',
  });

  $example->payload; # { height => 10, width => 20 }

DESCRIPTION

Role::HasPayload::Auto only provides one method, payload, which returns a hashref of the name and value of every attribute on the object with the Role::HasPayload::Meta::Attribute::Payload trait. (The attribute value is gotten with the the method returned by the attribute's get_read_method method.)

This role is especially useful when combined with Role::HasMessage::Errf.

PERL VERSION

This library should run on perls released even a long time ago. It should work on any version of perl released in the last five years.

Although it may work on older versions of perl, no guarantee is made that the minimum required version will not be increased. The version may be increased for any reason, and there is no promise that patches will be accepted to lower the minimum required perl.
