NAME
String::CityHash - CityHash wrapper for Perl
VERSION
version 0.02
SYNOPSIS
use String::CityHash qw(cityhash64);
my $str = "Some string to be hashed";
my $seed0 = 0x9ae16a3b2f90404f;
my $seed1 = 0xc3a5c85c97cb3130;
my $hash1 = cityhash64($str);
my $hash2 = cityhash64($str, $seed0);
my $hash3 = cityhash64($str, $seed0, $seed1);
my $hash4 = cityhash128($str);DESCRIPTION
CityHash is a family of non-cryptographic hash functions for strings. It provides hash functions designed for fast hashing of strings. The functions mix the input bits thoroughly but are not suitable for cryptography.
CityHash is intended to be fast, under the constraint that it hash very well.
EXPORTS
This module exports the subroutines cityhash64 and cityhash128 on request.
SUBROUTINES
cityhash64( $data [, $seed0 [, $seed1 ] ] )
Generate a 64-bit hash for the given data. The optional one or two 64-bit seeds are also hashed into the result.
