NAME

Types::UUID - type constraints for UUIDs

SYNOPSIS

package FroobleStick;

use Moo;
use Types::UUID;

has identifier => (
   is      => 'lazy',
   isa     => Uuid,
   coerce  => 1,
   builder => Uuid->generator,
);

DESCRIPTION

Types::UUID is a type constraint library suitable for use with Moo/Moose attributes, Kavorka sub signatures, and so forth.

Type

Currently the module only provides one type constraint, which is exported by default.

Uuid

A valid UUID string, as judged by the is_uuid_string() function provided by UUID::Tiny.

This constraint has coercions from Undef (generates a new UUID), Str (fixes slightly broken-looking UUIDs, adding missing dashes; also accepts base-64-encoded UUIDs) and URI objects using the urn:uuid: URI scheme.

Methods

The Uuid type constraint is actually blessed into a subclass of Type::Tiny, and provides an aditional method:

Uuid->generate

Generates a new UUID. Uuid->coerce(undef) would also work, but looks a little odd.

Uuid->generator

Returns a coderef which generates a new UUID. For an example usage, see the "SYNOPSIS".
