Functions

func Append

func Append(b []byte, i uint64) []byte

Append appends i in the QUIC varint format.

func AppendWithLen

func AppendWithLen(b []byte, i uint64, length protocol.ByteCount) []byte

AppendWithLen append i in the QUIC varint format with the desired length.

func Len

func Len(i uint64) protocol.ByteCount

Len determines the number of bytes that will be needed to write the number i.

func Read

func Read(r io.ByteReader) (uint64, error)

Read reads a number in the QUIC varint format from r.

func Write

func Write(w Writer, i uint64)

Write writes i in the QUIC varint format to w. Deprecated: use Append instead.

Types

type Reader

type Reader interface {
	io.ByteReader
	io.Reader
}

Reader implements both the io.ByteReader and io.Reader interfaces.

func NewReader

func NewReader(r io.Reader) Reader

NewReader returns a Reader for r. If r already implements both io.ByteReader and io.Reader, NewReader returns r. Otherwise, r is wrapped to add the missing interfaces.

type Writer

type Writer interface {
	io.ByteWriter
	io.Writer
}

Writer implements both the io.ByteWriter and io.Writer interfaces.

func NewWriter

func NewWriter(w io.Writer) Writer

NewWriter returns a Writer for w. If r already implements both io.ByteWriter and io.Writer, NewWriter returns w. Otherwise, w is wrapped to add the missing interfaces.
