Rust Random Number Generation Generating Characters with Rand
Example
To generate characters, you can utilize the thread-local random number generator function, random.
fn main() {
let tuple = rand::random::<(f64, char)>();
println!("{:?}", tuple)
}
For occasional or singular requests, such as the one above, this is a reasonable efficient method. However, if you intend to generate more than a handful of numbers, you will find caching the generator will be more efficient.
You should expect to the see the following output in this case.
$ cargo run
Running `target/debug/so`
