Overview 📖
Random (VRD)
is a Rust library for generating high-quality random numbers
based on the Mersenne Twister algorithm.
The Random
struct in this library provides a robust interface for generating
a variety of random numbers using the Mersenne Twister algorithm. Additionally,
the MersenneTwisterConfig
struct allows for advanced configuration of the
algorithm.
The Random (VRD) is used to generate random numbers using the Mersenne Twister algorithm. It generates pseudorandom integers uniformly distributed in 0..(2^32 - 1) starting from any odd seed in 0..(2^32 - 1).
The index is incremented after each random number is generated. When the index reaches 624, the array is reinitialized and the index is reset to 0.
Features ✨
- Create new random number generator and seed it with a value
- Designed for speed and efficiency
- Generate random 32-bit unsigned integers within a given range
- Provide random numbers of different types, including booleans, bytes, chars, doubles, floats, integers, and unsigned integers
- Mutate the state of the random number generator
- Produce pseudo-random number sequences that are different from each other
- Regulate the randomness of the generated numbers, including the seed value and the number of bits used
- Select a random element from a slice of values
- Generate random numbers from various probability distributions, including uniform, normal, exponential, and Poisson
Getting Started 🚀
It takes just a few minutes to get up and running with Random (VRD)
.
Installation
To install Random (VRD)
, you need to have the Rust toolchain installed on
your machine. You can install the Rust toolchain by following the instructions
on the Rust website.
Once you have the Rust toolchain installed, you can install Random (VRD)
using the following command:
cargo install vrd
Add the following to your Cargo.toml
file:
[dependencies]
vrd = "0.0.6"
serde = { version = "1.0.160", features = ["derive"] }
Usage
use vrd::random::Random;
let mut rng = Random::new();
let rand_int = rng.int(1, 10);
println!("Random integer between 1 and 10: {}", rand_int);
let rand_float = rng.float();
println!("Random float: {}", rand_float);
let rand_bytes = rng.bytes(10);
println!("Random bytes: {:?}", rand_bytes);
