NAME

       Sub::HandlesVia::Manual::WithMoo - using Sub::HandlesVia with Moo

SYNOPSIS

        package Kitchen {
          use Moo;
          use Sub::HandlesVia;
          use Types::Standard qw( ArrayRef Str );

          has food => (
            is          => 'ro',
            isa         => ArrayRef[Str],
            handles_via => 'Array',
            default     => sub { [] },
            handles     => {
              'add_food'    => 'push',
              'find_food'   => 'grep',
            },
          );
        }

MANUAL

       Sub::HandlesVia allows you to delegate methods from your class to the values of your
       objects' attributes.

       Conceptually, it allows you to define "$object->push_number($n)" to be a shortcut for
       "$object->numbers->push($n)" except that "$object->numbers" is an arrayref, so doesn't
       have methods you can call on it like "push".

       You should be able to use Sub::HandlesVia as a drop-in replacement for MooX::HandlesVia,
       which provides a similar feature, though has a more limited implementation.
       Sub::HandlesVia honours type constraints, plus it can mutate non-reference values.

   Which Methods Can Be Delegated To?
       The "handles_via" option indicates which library of methods should be available. Valid
       values include Array, Blessed, Bool, Code, Counter, Hash, Number, Scalar, and String.

       An arrayref can be provided for "handles_via", though many of the options are conceptually
       contradictory.

        handles_via => [ 'Number', 'Scalar' ]
