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''.
