What

This is not a pseudorandom number generator.

It is #![no_std] by nature with only core as dependency, and alloc if you use the informational feature distribution.

The generator can be seeded with the raw value of a pointer for semi-randomness.

You should take a look at the generator's distributions to see if this works for you.
