Orphan instances

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.

The nil UUID, as defined in RFC 4122. It is a UUID of all zeros. null u iff u == nil.

uuidNextRandom :: IO UUID Source #

uuidFromInteger :: Integer -> UUID Source #

Constructs a valid UUID from an Integer by padding with zeros. Useful for testing.
