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.
Random (VRD)
generates pseudorandom integers uniformly distributed in 0..(232 - 1), starting from any odd seed in 0..(232 - 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 a 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 pseudorandom 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.
Installation
Add this to your Cargo.toml
:
[]
= "0.0.8"
= { = "1.0.209", = ["derive"] }
Usage
Here's a quick example on how to use Random (VRD) to generate random numbers:
use Random;
let mut rng = new;
let rand_int = rng.int;
println!;
let rand_float = rng.float;
println!;
let rand_bytes = rng.bytes;
println!;

library provides a set of macros that simplify the usage of the library. These macros offer a convenient way to generate random numbers of different types and distributions.
Here are some of the available macros:
rand_bool!(rng, probability)
: Generate a random boolean with the provided probability.rand_bytes!(rng, length)
: Generate a vector of random bytes with the specified length.rand_char!(rng)
: Generate a random character within the range 'a'..='z'.rand_choose!(rng, values)
: Generate a random element from a slice of values.rand_float!(rng)
: Generate a random float.rand_int!(rng, min, max)
: Generate a random integer within the given range.rand_uint!(rng, min, max)
: Generate a random 32-bit unsigned integer within the given range.rand_double!(rng)
: Generate a random double.rand_string!(rng, length)
: Generate a random string of the specified length.rand_alphanumeric!(rng)
: Generate a random alphanumeric character.rand_shuffle!(rng, slice)
: Shuffle a mutable slice randomly.rand_weighted_choice!(rng, choices, weights)
: Select a random element from a slice based on the provided weights.rand_normal!(rng, mu, sigma)
: Generate a normally distributed random number with the given mean and standard deviation.rand_exponential!(rng, rate)
: Generate a random number from the exponential distribution with the given rate parameter.rand_poisson!(rng, mean)
: Generate a random number from a Poisson distribution with the specified mean parameter.
