NAME

       Type::Tiny::Manual::UsingWithMoo - how to use Type::Tiny and Type::Library with Moo

SYNOPSIS

          {
             package Person;

             use Moo;
             use Types::Standard qw( Str Int );
             use Type::Utils qw( declare as where inline_as coerce from );

             has name => (
                is      => "ro",
                isa     => Str,
             );

             my $PositiveInt = declare
                as        Int,
                where     {  $_ > 0  },
                inline_as { "$_ =~ /^[0-9]\$/ and $_ > 0" };

             coerce $PositiveInt, from Int, q{ abs $_ };

             has age => (
                is      => "rwp",
                isa     => $PositiveInt,
                coerce  => $PositiveInt->coercion,
             );

             sub get_older {
                my $self = shift;
                my ($years) = @_;
                $PositiveInt->assert_valid($years);
                $self->_set_age($self->age + $years);
             }
          }

DESCRIPTION

       Type::Tiny is tested with Moo 1.001000 and above.

       Type::Tiny overloads "&{}". Moo supports using objects that overload "&{}" as "isa"
       constraints, so Type::Tiny objects can directly be used in "isa".

       Moo doesn't support "coerce => 1" but requires a coderef as a coercion.  However, again it
       supports using objects that overload "&{}", which Type::Coercion does, allowing "coerce =>
       $Type->coercion" to work.

       Type::Tiny hooks into Moo's HandleMoose interface to ensure that type constraints get
       inflated to Moose type constraints if and when Moo inflates your class to a full Moose
       class.

   Optimization
       The usual advice for optimizing type constraints applies: use type constraints which can
       be inlined whenever possible, and define coercions as strings rather than coderefs.

       Upgrading to Moo 1.002000 or above should provide a slight increase in speed for type
       constraints, as it allows them to be inlined into accessors and constructors.

       If creating your own type constraints using "Type::Tiny->new", then consider using
       Sub::Quote to quote the coderef; this allows you to take advantage of inlining without
       having to write your own inlining routines.
