Crate twox_hash

A Rust implementation of the XXHash algorithm.

With a fixed seed

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

let mut hash: HashMap<_, _, BuildHasherDefault<XxHash>> = 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::RandomXxHashBuilder;

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

Structs

RandomXxHashBuilder

Constructs a randomized seed and reuses it for multiple hasher instances.

RandomXxHashBuilder32

Constructs a randomized seed and reuses it for multiple hasher instances. See the usage warning on XxHash32.

XxHash

Calculates the 64-bit hash.

XxHash32

Calculates the 32-bit hash. Care should be taken when using this hash.
