hash #
Description:
hash
provides a way to hash binary data, i.e. produce a shorter value, that is highly content dependent, so even slightly different content will produce widely different hashes.
Hash functions are useful for implementing maps, caches etc.
fn sum64 #
fn sum64(key []u8, seed u64) u64
sum64 returns a hash given a byte array key
and a seed
.
fn sum64_string #
fn sum64_string(key string, seed u64) u64
sum64_string returns a hash given a V string key
and a seed
.
fn wyhash64_c #
fn wyhash64_c(a u64, b u64) u64
wyhash64_c returns a hash given two u64 values a
and b
.
fn wyhash_c #
fn wyhash_c(key &u8, len u64, seed u64) u64
wyhash_c returns a hash given a byte string key
, its len
, and a seed
.
fn wymum #
fn wymum(a u64, b u64) u64
wymum returns a hash by performing multiply and mix on a
and b
.
