Trait Key 

pub trait Key: Copy + Eq {
    const VACANT: Self;

    // Required method
    fn hash(&self) -> u64;
}

A key a table can hold: its hash must be well mixed in the TOP bits.

Required Associated Constants

const VACANT: Self

Every bit set: what a vacant slot holds, so that emptying a table is one byte fill.

Required Methods

fn hash(&self) -> u64

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.
