Functions ¶

func DefaultInterpolate ¶

func DefaultInterpolate() func(uint64) uint64

func EnsureDir ¶

func EnsureDir(path string) error

EnsureDir checks if a directory exists at the given path. If the path exists and is a directory, it returns nil. If the path exists but is not a directory, it returns an error. If the path does not exist, it creates the directory and returns nil.

func HashU64 ¶

func HashU64(key uint64) (hash uint64)

HashU64 is an implementation of a Murmur3 algorithm, manually unwrapped.

func NewHashU64 ¶

func NewHashU64() func(uint64) uint64

NewHashU64 returns a new instance of a Murmur3 function. The returned function is not thread safe.

func NewInterpolateFunc ¶

func NewInterpolateFunc(sizeS, sizeL uint64, resizeS, resizeL float64) func(uint64) uint64
