Examples

With a fixed seed

use std::hash::BuildHasherDefault;
use std::collections::HashMap;
use twox_hash::XxHash64;

let mut hash: HashMap<_, _, BuildHasherDefault<XxHash64>> = Default::default();
hash.insert(42, "the answer");
assert_eq!(hash.get(&42), Some(&"the answer"));

With a random seed

use std::collections::HashMap;
use twox_hash::RandomXxHashBuilder64;

let mut hash: HashMap<_, _, RandomXxHashBuilder64> = Default::default();
hash.insert(42, "the answer");
assert_eq!(hash.get(&42), Some(&"the answer"));
