import {rapidhash} from 'rapidhash-js';

// rapidhash() returns a 64-bit hash value represented as bigint.
console.log(rapidhash('hello world'));  // Output: 17498481775468162579n

// You can specify a 64-bit seed value with the 'seed' option.
console.log(rapidhash('hello world', {seed: 0x0123_4567_89AB_CDEFn}));  // Output: 9400866032237060842n

// You can specify the behavior of the rapid_mum() function
// with the rapidMumBehaviour option (default is 'fast').
console.log(rapidhash('hello world', {rapidMumBehaviour: 'protected'}));  // Output: 16019612682927597028n

// Instead of specifying the rapidMumBehaviour option,
// you can call rapidhash_fast() or rapidhash_protected().
console.log(rapidhash_protected('hello world'));
