Variables

var ErrBufTooSmall = errors.New("varint: buf too small")

ErrBufTooSmall is returned when there is not enough data for parsing a varint.

Functions

func EncodedSize

func EncodedSize(n uint64) (size int)

EncodedSize returns the size required to varint-encode an uint.

func GetNextBlock

func GetNextBlock(data []byte) ([]byte, int, error)

GetNextBlock extract the integer from the beginning of the given byte slice and returns the remaining bytes, the extracted integer, and whether there was an error.

func Pack16

func Pack16(n uint16) []byte

Pack16 packs a uint16 into a VarInt.

func Pack32

func Pack32(n uint32) []byte

Pack32 packs a uint32 into a VarInt.

func Pack64

func Pack64(n uint64) []byte

Pack64 packs a uint64 into a VarInt.

func Pack8

func Pack8(n uint8) []byte

Pack8 packs a uint8 into a VarInt.

func PrependLength

func PrependLength(data []byte) []byte

PrependLength prepends the varint encoded length of the byte slice to itself.

func Unpack16

func Unpack16(blob []byte) (uint16, int, error)

Unpack16 unpacks a VarInt into a uint16. It returns the extracted int, how many bytes were used and an error.

func Unpack32

func Unpack32(blob []byte) (uint32, int, error)

Unpack32 unpacks a VarInt into a uint32. It returns the extracted int, how many bytes were used and an error.

func Unpack64

func Unpack64(blob []byte) (uint64, int, error)

Unpack64 unpacks a VarInt into a uint64. It returns the extracted int, how many bytes were used and an error.

func Unpack8

func Unpack8(blob []byte) (uint8, int, error)

Unpack8 unpacks a VarInt into a uint8. It returns the extracted int, how many bytes were used and an error.
