How to do it...

We can obtain randomness in just a few steps:

1. Open a Terminal to create a new project using cargo new random-numbers --lib. Use VS Code to open the project directory.
2. First, we need to add the rand crate as a dependency in Cargo.toml. Open it to add the following:

[dependencies]rand = {version = "0.7", features = ["small_rng"]}rand_distr = "0.2"rand_pcg = "0.2"

3. Since we are exploring how to use the rand library, we are going to add to the test module and implement three tests. Let's start by replacing the default content in src/lib.rs with some required imports:

#[cfg(test)]mod tests {    use rand::prelude::*;    use rand::SeedableRng;    use rand_distr::{Bernoulli, Distribution, Normal, Uniform};}

4. Right underneath the imports ...
