NAME
Sub::HandlesVia::HandlerLibrary::Scalar - library of scalar-related methods

SYNOPSIS
  package My::Class {
    use Moo;
    use Sub::HandlesVia;
    use Types::Standard 'Any';
    has attr => (
      is => 'rwp',
      isa => Any,
      handles_via => 'Scalar',
      handles => {
        'my_get' => 'get',
        'my_make_getter' => 'make_getter',
        'my_make_setter' => 'make_setter',
        'my_scalar_reference' => 'scalar_reference',
        'my_set' => 'set',
        'my_stringify' => 'stringify',

    );
  }

DESCRIPTION
This is a library of methods for Sub::HandlesVia.

DELEGATABLE METHODS

  get()
Gets the current value of the scalar.

  make_getter()
Returns a getter coderef.

  my $object = My::Class->new( attr => 10 );
  my $getter = $object->my_make_getter;
  $object->_set_attr( 11 );
  say $getter->(); ## ==> 11

  make_setter()
Returns a setter coderef.

  my $object = My::Class->new( attr => 10 );
  my $setter = $object->my_make_setter;
  $setter->( 11 );
  say $object->attr; ## ==> 11

  scalar_reference()
Returns a scalar reference to the attribute value's slot within its object.

  my $object = My::Class->new( attr => 10 );
  my $ref = $object->my_scalar_reference;
  $$ref++;
  say $object->attr; ## ==> 11

  set( $value )
Sets the scalar to a new value.

  stringify()
Gets the current value of the scalar, but as a string.
