Trait DeepVariants 

pub trait DeepVariants: Sized + 'static {
    const DEEP_VARIANTS: &'static [Self];
}

Types that expose every reachable value as a compile-time constant slice.

The companion DeepVariants derive macro implements this trait for an enum whose variants are either unit variants or singleton tuple variants over types that also implement DeepVariants.

Example

use enum_tree::DeepVariants;

#[derive(DeepVariants, PartialEq, Eq, Debug)]
enum Light
{
    Red,
    Yellow,
    Green,
}

assert_eq!(
    Light::DEEP_VARIANTS,
    &[Light::Red, Light::Yellow, Light::Green]
);

Required Associated Constants

const DEEP_VARIANTS: &'static [Self]

The flat list of every reachable variant value.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
