Enum-Derived

Enum-Derived is a collection of derive macros that extend the functionality of enums

Rand

Rand allows for a random variant of an enum to be generated. This can be particularly useful when testing and the specific variant isn't important.

```rust use enum_derived::Rand;

[derive(Rand, Debug)]

pub enum Dna { A, C, T, G }

fn main() {

let base = Dna::rand();

println!("Random Base: ${base:?}");

} ```

Two examples where the rand method is only available in tests.

Vehicle::rand() is not available in main()

```compile_fail

[cfg(test)]

use enum_derived::Rand;

[cfg_attr(test, Rand)]

[derive(Debug)]

pub enum Vehicle { Car, Truck, Motorbike, }

fn main() { let vehicle = Vehicle::rand(); }

```

Vehicle::rand() is available in the tests module

```rust

[cfg(test)]

use enum_derived::Rand;

[cfg_attr(test, Rand)]

[derive(Debug)]

pub enum Vehicle { Car, Truck, Motorbike, }

[cfg(test)]

mod tests { use super::*;

#[test]
fn random_vehicle() {
    let vehicle = Vehicle::rand();
}

} ```
