Macro hash_length

macro_rules! hash_length {
    ($hash:expr) => { ... };
}

This macro returns the length of the password for a given Hash struct instance.

Example

extern crate hsh;
use hsh::models::{hash::Hash, hash_algorithm::{HashAlgorithm}};
use hsh::{ hash_length, new_hash };


let password = "password";
let salt = "salt";
let algo = "bcrypt";

let hash = new_hash!(password, salt, algo);
assert!(hash.is_ok());
let hash = hash.unwrap();

let password_length = hash_length!(hash);
assert_eq!(password_length, 60);
