Data.UUID.V1

Description

RFC 4122 Version 1 UUID state machine.

The generated UUID is based on the hardware MAC address and the system clock.

If we cannot lookup the MAC address we seed the generator with a pseudo-random number.

Synopsis

- nextUUID :: IO (Maybe UUID)

# Documentation

nextUUID :: IO (Maybe UUID) #

Returns a new UUID derived from the local hardware MAC address and the current system time. Is generated according to the Version 1 UUID specified in RFC 4122.

Returns `Nothing` if you request UUIDs too quickly.
