Function `random_range`

fn random_range<T, R>(range: R) -> T
where
    T: distr::uniform::SampleUniform,
    R: distr::uniform::SampleRange<T>

Generate a random value in the given range using the thread-local random number generator.

This function is shorthand for [rng()].random_range(range).

Example

let y: f32 = rand::random_range(0.0..=1e9);
println!("{}", y);

let words: Vec<&str> = "Mary had a little lamb".split(' ').collect();
println!("{}", words[rand::random_range(..words.len())]);

Note that the first example can also be achieved (without collect'ing to a Vec) using seq::IteratorRandom::choose.
