Trait DictKey 

pub trait DictKey {
    type Array<T>: Array<T>;

    const VARIANTS: &'static [&'static str];

    // Required methods
    fn from_index(index: usize) -> Self;
    fn as_index(&self) -> usize;
}

Trait for types that can be used as dictionary keys

Required Associated Constants

const VARIANTS: &'static [&'static str]

Required Associated Types

type Array<T>: Array<T>

Required Methods

fn from_index(index: usize) -> Self

fn as_index(&self) -> usize
