NAME
MooX::Types::MooseLike::Base - Moose like types for Moo
SYNOPSIS
package MyPackage;
use Moo;
use MooX::Types::MooseLike::Base qw(:all);
has "beers_by_day_of_week" => (
isa => HashRef
);
has "current_BAC" => (
isa => Num
);
# Also supporting is_$type. For example, is_Int() can be used as follows
has 'legal_age' => (
is => 'ro',
isa => sub { die "$_[0] is not of legal age"
unless (is_Int($_[0]) && $_[0] > 17) },
);DESCRIPTION
Moo attributes (like Moose) have an 'isa' property. This module provides some basic types for this property. One can import all types with ':all' tag or import a list of types like:
use MooX::Types::MooseLike::Base qw/HashRef CodeRef/;so one could then declare some attributtes like:
has 'contact' => (
is => 'ro',
isa => HashRef,
);
has 'guest_list' => (
is => 'ro',
isa => ArrayRef,
);These types provide a check that the contact attribute is a hash reference, and that the guest_list is an array reference.

mst provided the implementation suggestion of using 'can' on a quoted sub to define a type (subroutine).
