Note

The x86 and x64 versions do not produce the same results, as the algorithms are optimized for their respective platforms. You can still compile and run any of them on any platform, but your performance with the non-native version will be less than optimal.

Example

use std::hash::{Hash, Hasher};

use fasthash::{murmur3, Murmur3HasherExt};

fn hash<T: Hash>(t: &T) -> u64 {
    let mut s: Murmur3HasherExt = Default::default();
    t.hash(&mut s);
    s.finish()
}

let h = murmur3::hash128(b"hello world\xff");

assert_eq!(h as u64, hash(&"hello world"));

Structs

Hash32	MurmurHash3 32-bit hash functions
Hash128_x64	MurmurHash3 128-bit hash functions for 64-bit processors
Hash128_x86	MurmurHash3 128-bit hash functions for 32-bit processors
Hasher32	An implementation of std::hash::Hasher.
Hasher128_x64	An implementation of std::hash::Hasher and fasthash::HasherExt.
Hasher128_x86	An implementation of std::hash::Hasher and fasthash::HasherExt.

Functions

hash32	MurmurHash3 32-bit hash functions for a byte array.
hash32_with_seed	MurmurHash3 32-bit hash functions for a byte array. For convenience, a 32-bit seed is also hashed into the result.
hash128	MurmurHash3 128-bit hash functions for a byte array.
hash128_with_seed	MurmurHash3 128-bit hash functions for a byte array. For convenience, a 32-bit seed is also hashed into the result.
