Functions

func BoolFromByteArray

func BoolFromByteArray(v []byte) (bool, error)

BoolFromByteArray converts a BigEndian byte array to a bool

func BoolToByteArray

func BoolToByteArray(v bool) []byte

BoolToByteArray converts a bool to a byte array

func ConcatByteArrays

func ConcatByteArrays(arrays ...[]byte) []byte

ConcatByteArrays concatenates a number of byte arrays

func GenerateFileWithTestData

func GenerateFileWithTestData(filePath string, data []byte) (*os.File, error)

GenerateFileWithTestData creates a file at the given filePath if it does not exist and adds the given data overwriting any pre-existing data

func GetFileSize

func GetFileSize(file *os.File) (uint64, error)

GetFileSize computes the file size of the given file

func GetHash

func GetHash(key []byte, blockLength uint64) uint64

GetHash generates the hash of the key for the given block length to get the position in the block that the given key corresponds to

func PathExists
