package base128

import "go.chromium.org/luci/common/data/base128"

Package base128 implements base128 encoding and decoding.

Encoded results are UTF8-safe, and will retain the same memcmp sorting properties of the input data.

Variables ¶

var (
    // ErrLength is returned from the Decode* methods if the input has an
    // impossible length.
    ErrLength = errors.New("base128: invalid length base128 string")

    // ErrBit is returned from the Decode* methods if the input has a byte with
    // the high-bit set (e.g. 0x80). This will never be the case for strings
    // produced from the Encode* methods in this package.
    ErrBit = errors.New("base128: high bit set in base128 string")
)

func Decode ¶ Uses

func Decode(dst, src []byte) (int, error)

Decode decodes src into DecodedLen(len(src)) bytes, returning the actual number of bytes written to dst.

If Decode encounters invalid input, it returns an error describing the failure.

func DecodeString ¶ Uses

func DecodeString(s string) ([]byte, error)

DecodeString returns the bytes represented by the base128 string s.

func DecodedLen ¶ Uses

func DecodedLen(encLen int) int

DecodedLen returns the number of bytes `encLen` encoded bytes decodes to.

func Encode ¶ Uses

func Encode(dst, src []byte) int

Encode encodes src into EncodedLen(len(src)) bytes of dst. As a convenience, it returns the number of bytes written to dst, but this value is always EncodedLen(len(src)).

Encode implements base128 encoding.

func EncodeToString ¶ Uses

func EncodeToString(src []byte) string

EncodeToString returns the base128 encoding of src.

func EncodedLen ¶ Uses

func EncodedLen(dataLen int) int

EncodedLen returns the number of bytes that `dataLen` bytes will encode to.
