Module rand

Source
Expand description

Random number generation.

This module defines several types:

  • RNG algorithms specialized for 8-bit devices: Xabc, Xyza8a, Xyza8b.
  • Classic XorShift algorithms and variations with a smaller state.

The RNGs implement Copy for convenience and versatility. Be careful to not duplicate the state by accident.

The Default implementation uses a fixed seed for convenience. Use a custom seed for unique random sequences.

§Features

All PRNGs require the rand feature, except for XorShift128p, which is always compiled.

Macros§

xorshift_customrand
