Functions

func DecodeSLeb128

func DecodeSLeb128(value []byte) int64

DecodeSLeb128 decodes a signed LEB128 value to a signed int64 value. Returns the result as a int64

func DecodeULeb128

func DecodeULeb128(value []byte) uint64

DecodeULeb128 decodes an unsigned LEB128 value to an unsigned int64 value. Returns the result as a uint64

func EncodeSLeb128

func EncodeSLeb128(value int64) []byte

EncodeSLeb128 encode a signed int64 value to a signed LEB128 value. Returns the result in a byte slice

func EncodeULeb128

func EncodeULeb128(value uint64) []byte

EncodeULeb128 encode's an unsigned int64 value to an unsigned LEB128 value. Returns the result in a byte slice

func ReadSLeb128

func ReadSLeb128(reader io.ByteReader) int64

ReadSLeb128 reads and decodes a signed LEB128 value from a ByteReader to a signed int64 value. Returns the result as a int64

func ReadULeb128

func ReadULeb128(reader io.ByteReader) (uint64, error)

ReadULeb128 reads and decodes an unsigned LEB128 value from a ByteReader to an unsigned int64 value. Returns the result as a uint64
