Trait Variants 

pub trait Variants: Copy + 'static {
    const TYPE: &'static str;
    const VARIANTS: &'static [(&'static str, Self)];
    const PATH: &'static str = Self::TYPE;
    const TRANSITIONS: &'static [(Self, Self)] = _;

    // Provided methods
    fn name(self) -> &'static str { ... }
    fn to(self, next: Self, field: &str) -> Result<Self> { ... }
}

Required Associated Constants

const TYPE: &'static str

const VARIANTS: &'static [(&'static str, Self)]

Provided Associated Constants

const PATH: &'static str = Self::TYPE

Module-qualified, so two enums of one name keep their recorded moves apart.

const TRANSITIONS: &'static [(Self, Self)] = _

Provided Methods

fn name(self) -> &'static str

fn to(self, next: Self, field: &str) -> Result<Self>

A refused move is an error on field, the one holding the value.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
