Trait HashDef 

pub trait HashDef: Sized {
    type Hash: Sized;

    const HASHER: fn(&str) -> Self::Hash;

    // Required methods
    fn new(hash: Self::Hash) -> Self;
    fn is_null(&self) -> bool;

    // Provided method
    fn hashed(s: &str) -> Self { ... }
}

Trait for hash values types

This trait is implemented by types created with crate::define_hash_type!().

Required Associated Constants

const HASHER: fn(&str) -> Self::Hash

Hashing method

Required Associated Types

type Hash: Sized

Type of hash values (integer type)

Required Methods

fn new(hash: Self::Hash) -> Self

Create a new hash value from an integer

fn is_null(&self) -> bool

Return true if hash is the null hash (0)

Provided Methods

fn hashed(s: &str) -> Self

Convert a string into a hash by hashing it

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.
