Rng Struct Reference

Inheritance diagram for Rng:

Detailed Description

A wrapper around random number generators.

We need this to abstract away the different implementations of randomness under different environments:

1. The TUI and the CLI use the rand function from the standard C library.
2. The GUI has BetterRng which wraps the standard C++ functions from <random>.
3. The test suite calls munit_rand_int_range (see https://nemequ.github.io/munit/#prng).

The struct itself provides pointers to the actual functions of randomness implementations, so it works kind of like an interface in OOP terminology.
