func AppendFixed32

func AppendFixed32(b []byte, v uint32) []byte

AppendFixed32 appends v to b as a little-endian uint32.

func AppendFixed64

func AppendFixed64(b []byte, v uint64) []byte

AppendFixed64 appends v to b as a little-endian uint64.

func AppendVarint

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

VarintEncode encodes a uint64 value as a varint-encoded byte slice. AppendVarint appends v to b as a varint-encoded uint64.

func ConsumeBytes

func ConsumeBytes(b []byte) (v []byte, n int, all int)

ConsumeBytes parses b as a length-prefixed bytes value, reporting its length. This returns a negative length upon an error (see ParseError).

func ConsumeFixed32

func ConsumeFixed32(b []byte) (v uint32, n int)

ConsumeFixed32 parses b as a little-endian uint32, reporting its length. This returns a negative length upon an error (see ParseError).

func ConsumeFixed64

func ConsumeFixed64(b []byte) (v uint64, n int)

ConsumeFixed64 parses b as a little-endian uint64, reporting its length. This returns a negative length upon an error (see ParseError).

func ConsumeVarint

func ConsumeVarint(b []byte) (v uint64, n int)

ConsumeVarint parses b as a varint-encoded uint64, reporting its length. This returns a negative length upon an error (see ParseError).

func DecodeZigZag

func DecodeZigZag(x uint64) int64

DecodeZigZag decodes a zig-zag-encoded uint64 as an int64.

Input:  {…,  5,  3,  1,  0,  2,  4,  6, …}
Output: {…, -3, -2, -1,  0, +1, +2, +3, …}

func EncodeZigZag

func EncodeZigZag(v int64) uint64

EncodeZigZag encodes an int64 as a zig-zag-encoded uint64.

Input:  {…, -3, -2, -1,  0, +1, +2, +3, …}
Output: {…,  5,  3,  1,  0,  2,  4,  6, …}

func SizeFixed32

func SizeFixed32() int

SizeFixed32 returns the encoded size of a fixed32; which is always 4.

func SizeFixed64

func SizeFixed64() int

SizeFixed64 returns the encoded size of a fixed64; which is always 8.

func SizeVarint

func SizeVarint(v uint64) int

SizeVarint returns the encoded size of a varint. The size is guaranteed to be within 1 and 10, inclusive.
