       Role::HasMessage::Errf - a thing with a String::Errf-powered message


       version 0.006


       In your class...

         package Errfy;
         use Moose;

         with 'Role::HasMessage::Errf';

         has payload => (
           is  => 'ro',
           isa => 'HashRef',
           required => 1,


         my $thing = Errfy->new({
           message => "%{error_count;error}n encountered at %{when}t",
           payload => {
             error_count => 2,
             when        => time,

         # prints: 2 errors encountered at 2010-10-20 19:23:42
         print $thing->message;


       Role::HasMessage::Errf is an implementation of Role::HasMessage that uses String::Errf to
       format "sprintf"-like message strings.  It adds a "message_fmt" attribute, initialized by
       the "message" argument.  The value should be a String::Errf format string.

       When the provided "message" method is called, it will fill in the format string with the
       hashref returned by calling the "payload" method, which must be implemented by the
       including class.

       Role::HasMessage::Errf is a parameterized role.  The "default" parameter lets you set a
       default format string or callback.  The "lazy" parameter sets whether or not the
       "message_fmt" attribute is lazy.  Setting it lazy will require that a default is provided.
