Trait identity_core::common::KeyComparable

pub trait KeyComparable {
    type Key: PartialEq + ?Sized;

    // Required method
    fn key(&self) -> &Self::Key;
}

A trait for comparing types only by a certain key.

Required Associated Types

type Key: PartialEq + ?Sized

Key type for comparisons.

Required Methods

fn key(&self) -> &Self::Key

Returns a reference to the key.

Object Safety

This trait is not object safe.
