RNG Pack

A collection of random number generators.

This crate provides implementations of various pseudo-random number generators (PRNGs), including:

• Mersenne Twister: rng32::Mt19937 (32-bit), rng64::Mt1993764 (64-bit).
• Permuted Congruential Generator: rng32::Pcg32 (32-bit output).
• Philox: rng32::Philox32 (4x32-bit), rng64::Philox64 (2x64-bit).
• Twisted Generalized Feedback Shift Register: rng64::TwistedGFSR (64-bit).
• Small Fast Chaotic: rng64::Sfc64 (64-bit).
• Xorshift: rng32::Xorshift32 (32-bit), rng64::Xorshift64 (64-bit), rng128::Xorshift128 (128-bit state).
• Xorwow: rng32::Xorwow (32-bit).
• Xoshiro: rng64::Xoshiro256Pp, rng64::Xoshiro256Ss (64-bit).
• Linear Congruential Generator: rng32::Lcg32 (32-bit), rng64::Lcg64 (64-bit).
• Cellular Automata: rng64::Cet64 (64-bit).
• SplitMix: rng32::SplitMix32 (32-bit), rng64::SplitMix64 (64-bit).

Macros

• Random Generation: next!, rand!
• Utilities: wrap!, search!, choice!

Each generator supports generating uniform random numbers for various types (u32, u64, f32, f64) and ranges.

C API

This crate also exports C-compatible functions for creating, using, and freeing these generators, allowing them to be used from other languages.
