tango.util.uuid.RandomGen

Most people who want UUIDs will generate small numbers of them (maybe a few hundred thousand) and not require a huge amount of uniqueness (just for this one application). This module provides a convenient way to obtain that behavior.
To streamline your usage, this module publicly imports Uuid, so you can import this module alone.

To use this module, just:

import tango.util.uuid.RandomGen;

Uuid id = randUuid.next;
UuidGen randUuid ΒΆ
The default random UUID generator. You can set this if you need to generate UUIDs in another manner and already have code pointing to this module.
This uses a unique PRNG instance. If you want repeatable results, you should inject your own UUID generator and reseed it as necessary:

auto rand = getRand();
randUuid = new RandomGen!(typeof(rand))(rand);
doStuff();
rand.reseed();

The default PRNG is the Mersenne twister. If you need speed, KISS is about 30 times faster. I chose the Mersenne twister because it's reasonably fast (I can generate 150,000 per second on my machine) and has a long period. The KISS generator can produce 5 million per second on my machine.
