Overview

Package hack gives you some efficient functionality at the cost of breaking some Go rules.

Functions

func RuntimeMemhash

func RuntimeMemhash(b []byte, seed uint64) uint64

RuntimeMemhash provides access to the Go runtime's default hash function for arbitrary bytes. This is an optimal hash function which takes an input seed and is potentially implemented in hardware for most architectures. This is the same hash function that the language's `map` uses.

func RuntimeStrhash

func RuntimeStrhash(str string, seed uint64) uint64

RuntimeStrhash provides access to the Go runtime's default hash function for strings. This is an optimal hash function which takes an input seed and is potentially implemented in hardware for most architectures. This is the same hash function that the language's `map` uses.

func String

func String(b []byte) (s string)

String force casts a []byte to a string. USE AT YOUR OWN RISK

func StringPointer

func StringPointer(s string) unsafe.Pointer

StringPointer returns &s[0], which is not allowed in go
