Functions

func AppendSleb128

func AppendSleb128(b []byte, v int64) []byte

AppendSleb128 appends v to b using signed LEB128 encoding.

func AppendUleb128

func AppendUleb128(b []byte, v uint64) []byte

AppendUleb128 appends v to b using unsigned LEB128 encoding.

func ReadVarUint32

func ReadVarUint32(r io.Reader) (uint32, error)

ReadVarUint32 reads a LEB128 encoded unsigned 32-bit integer from r, and returns the integer value, and the error (if any).

func ReadVarint32

func ReadVarint32(r io.Reader) (int32, error)

ReadVarint32 reads a LEB128 encoded signed 32-bit integer from r, and returns the integer value, and the error (if any).

func ReadVarint64

func ReadVarint64(r io.Reader) (int64, error)

ReadVarint64 reads a LEB128 encoded signed 64-bit integer from r, and returns the integer value, and the error (if any).

func WriteVarUint32

func WriteVarUint32(w io.Writer, cur uint32) (int, error)

WriteVarUint32 writes a LEB128 encoded unsigned 32-bit integer to w. It returns the integer value, the size of the encoded value (in bytes), and the error (if any).

func WriteVarint64

func WriteVarint64(w io.Writer, cur int64) (int, error)

WriteVarint64 writes a LEB128 encoded signed 64-bit integer to w, and returns the integer value, the size of the encoded value, and the error (if any)
