Implementations

impl CityHash128Hasher

pub fn with_seed(seed: u128) -> CityHash128Hasher

Create a new CityHash128Hasher initiated with a hash key

Trait Implementations

impl BuildHasher for CityHash128Hasher

fn build_hasher(&self) -> Self::Hasher

Creates a new CityHash128Hasher.

type Hasher = CityHash128Hasher

Type of the hasher that will be created.

fn hash_one<T>(&self, x: T) -> u64 where
    T: Hash, 

🔬 This is a nightly-only experimental API. (build_hasher_simple_hash_one)

Calculates the hash of a single value.

impl Debug for CityHash128Hasher

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CityHash128Hasher

fn default() -> CityHash128Hasher

Returns the “default value” for a type.

impl Hasher for CityHash128Hasher

fn finish(&self) -> u64

Returns the hash value for the values written so far. The hash is compress to a 64-bits with city_hash_128_to_64

Example

use cityhash_sys::CityHash128Hasher;
use core::hash::Hasher;

let hasher = CityHash128Hasher::with_seed(0xAAAAAAAAAAAAAAAABBBBBBBBBBBBBBBB);
