get random enum rust

To get a random enum value in Rust, you can use the rand crate and its Rng trait. First, add the rand crate to your Cargo.toml file:

[dependencies]
rand = "0.8"

Then, in your code, you can use the rand::Rng trait to generate a random enum value. Here's an example:

use rand::Rng;

#[derive(Debug)]
enum MyEnum {
    Variant1,
    Variant2,
    Variant3,
}

fn main() {
    let mut rng = rand::thread_rng();

    let random_enum: MyEnum = match rng.gen_range(0..=2) {
        0 => MyEnum::Variant1,
        1 => MyEnum::Variant2,
        _ => MyEnum::Variant3,
    };

    println!("{:?}", random_enum);
}

In this example, we import the Rng trait from the rand crate and define an enum called MyEnum with three variants. Inside the main function, we create a rand::thread_rng() instance to generate random numbers. We then use the gen_range method to generate a random number between 0 and 2 (inclusive). Based on the generated number, we match it to one of the enum variants and assign the result to the random_enum variable. Finally, we print the value of random_enum.

This code will output a random enum variant each time it is run.
