NAME

Data::Rx::TypeBundle::Rx - Build types from Data::Rx schema (experimental)

VERSION

version 0.103520

SYNOPSIS

use Data::Rx;
use Data::Rx::TypeBundle::Rx;

my $custom_type_library = Data::Rx::TypeBundle::Rx->new;
$custom_type_library->register_type('tag:example.com:rx/pos', {
    type => '//num',
    range => { 'min-ex' => 0 },
});

$custom_type_library->register_type('tag:example.com:rx/neg', {
    type => '//num',
    range => { 'max-ex' => 0 },
});

my $rx = Data::Rx->new({
    prefix       => { ext => 'tag:example.com:rx/' },
    type_plugins => [ $custom_type_lib ],
});

my $pos_checker = $rx->make_schema({ type => '/ext/pos' });

$pos_checker->check(10);  # OK
$pos_checker->check(0);   # NOT OK
$pos_checker->check(-10); # NOT OK

my $neg_checker = $rx->make_schema({ type => '/ext/neg' });

$neg_checker->check(10);  # NOT OK
$neg_checker->check(0);   # NOT OK
$neg_checker->check(-10); # OK

DESCRIPTION

This provides tools for creating Data::Rx type definitions. This is really just a way for creating reusable type aliases.

METHODS

new

my $type_library = Data::Rx::TypeBundle::Rx->new;

Constructs a new type library object.

register_type

$type_library->register_type($type_uri, $definition);

This registers a new Rx type alias. The $type_uri should be the namespace to assign the type to and the $definition should be a Data::Rx schema definition to assign to that type.

type_plugins

Used by Data::Rx. Returns all of the Data::Rx::Type::Rx type plugins that have been registered.

CAVEATS

The one thing you do need to beware of is that all of your types need to be registered before passing this object off to Data::Rx. Any types registered after passing this object to the Data::Rx constructor or "register_type_plugin" in Data::Rx method will not be known to Data::Rx.
