Eventful.UUID

Contents

Description

This module contains orphan UUID instances and a few convenience functions around UUIDs. It would be great if this were its own entirely separate package.

Synopsis

Documentation

data UUID :: * #

The UUID type. A Random instance is provided which produces version 4 UUIDs as specified in RFC 4122. The Storable and Binary instances are compatible with RFC 4122, storing the fields in network order as 16 bytes.
