Types::UUID - type constraints for UUIDs

   package FroobleStick;
   
   use Moo;
   use Types::UUID;
   
   has identifier => (
      is      => 'lazy',
      isa     => Uuid,
      coerce  => 1,
      builder => Uuid->generator,
   );

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

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.

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".

Please report any bugs to <http://rt.cpan.org/Dist/Display.html?Queue=Types-UUID>.
