Trait Identity 

pub trait Identity<K>
where
    K: Identifier,
{
    type Item: Borrow<K>;

    // Required method
    fn get(&self) -> &Self::Item;
}

The Id trait describes the behavior of a type that can be used as an id. An Id is almost identical to an Identifier, but it is a trait that can be implemented for any type.

Required Associated Types

Required Methods

fn get(&self) -> &Self::Item

Implementors

impl<K, S> Identity<K> for S

where S: Borrow<K>, K: Identifier,

type Item = S
