fl::fl_random Class Reference

Detailed Description

A random number generator class that wraps FastLED's random functions.

This class provides a standard C++ random generator interface that can be used with algorithms like fl::shuffle. Each instance maintains its own seed state independent of other instances and the global FastLED random state.

fl::fl_random rng;
fl::vector<int> vec = {1, 2, 3, 4, 5};
fl::shuffle(vec.begin(), vec.end(), rng);
