Universal RNG

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).
• SIMD-oriented Fast Mersenne Twister: rng32::Sfmt19937 (32-bit), rng64::Sfmt1993764 (64-bit).
• Permuted Congruential Generator: rng32::Pcg32 (32-bit output).
• Philox: rng32::Philox32x4 (4x32-bit), rng64::Philox64 (2x64-bit).
• Twisted Generalized Feedback Shift Register: rng64::TwistedGFSR (64-bit).
• Small Fast Chaotic: rng64::Sfc64 (64-bit).
• Threefry: rng32::Threefry32x4 (4x32-bit), rng32::Threefry32x2 (2x32-bit).
• Threefish: rng64::Threefish256 (256-bit block cipher PRNG).
• Xorshift: rng32::Xorshift32 (32-bit), rng64::Xorshift64 (64-bit), [rng128::Xorshift128] (128-bit state).
• Xorwow: rng32::Xorwow (32-bit).
• Xoshiro (32-bit): rng32::Xoshiro128Pp, rng32::Xoshiro128Ss.
• Xoshiro (64-bit): rng64::Xoshiro256Pp, rng64::Xoshiro256Ss.
• Xoroshiro: rng64::xoroshiro::Xoroshiro128Pp, rng64::xoroshiro::Xoroshiro128Ss (64-bit).
• Linear Congruential Generator: rng32::Lcg32 (32-bit), rng64::Lcg64 (64-bit).
• Cet: rng64::Cet64 (64-bit), rng64::Cet256 (256-bit state).
• SplitMix: rng32::SplitMix32 (32-bit), rng64::SplitMix64 (64-bit).
• Jenkins Small Fast: rng32::Jsf32 (32-bit).

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