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, Murmur3Hasher};

fn hash<T: Hash>(t: &T) -> u64 {
    let mut s: Murmur3Hasher = Default::default();
    t.hash(&mut s);
    s.finish()
}

let h = murmur3::hash128(b"hello world\xff").low64();

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

Structs

Murmur3Hasher_x64_128	An implementation of `std::hash::Hasher` and `fasthash::HasherExt`.
Murmur3Hasher_x86_32	An implementation of `std::hash::Hasher`.
Murmur3Hasher_x86_128	An implementation of `std::hash::Hasher` and `fasthash::HasherExt`.
Murmur3_x64_128	`MurmurHash3` 128-bit hash functions for 64-bit processors
Murmur3_x86_32	`MurmurHash3` 32-bit hash functions
Murmur3_x86_128	`MurmurHash3` 128-bit hash functions for 32-bit processors

Functions

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