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::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"));

Re-exports

pub use crate::xxh3::Hash128 as Xxh3Hash128;
pub use crate::xxh3::Hash64 as Xxh3Hash64;

Structs

RandomXxHashBuilder32	Constructs a randomized seed and reuses it for multiple hasher instances. See the usage warning on XxHash32.
RandomXxHashBuilder64	Constructs a randomized seed and reuses it for multiple hasher instances.
RandomXxh3HashBuilder64	Constructs a randomized seed and reuses it for multiple hasher instances.
RandomXxh3HashBuilder128	Constructs a randomized seed and reuses it for multiple hasher instances.
XxHash32	Calculates the 32-bit hash. Care should be taken when using this hash.
XxHash64	Calculates the 64-bit hash.
