Functions

func HashData

func HashData(src io.Reader) (string, error)

func NewBufReader

func NewBufReader(r io.Reader) *bufReader

func NewBufReaderWithDrainbufAndBuffer

func NewBufReaderWithDrainbufAndBuffer(r io.Reader, drainBuffer []byte, buffer *bytes.Buffer) *bufReader

func NewReadCloserWrapper

func NewReadCloserWrapper(r io.Reader, closer func() error) io.ReadCloser

func NewReaderErrWrapper

func NewReaderErrWrapper(r io.Reader, closer func()) io.Reader

func NewWriteCloserWrapper

func NewWriteCloserWrapper(r io.Writer, closer func() error) io.WriteCloser

func NopWriteCloser

func NopWriteCloser(w io.Writer) io.WriteCloser

Types

type NopFlusher

type NopFlusher struct{}

func (*NopFlusher) Flush

func (f *NopFlusher) Flush()

type NopWriter

type NopWriter struct{}

func (*NopWriter) Write

func (*NopWriter) Write(buf []byte) (int, error)

type WriteCounter

type WriteCounter struct {
	Count  int64
	Writer io.Writer
}

Wrap a concrete io.Writer and hold a count of the number of bytes written to the writer during a "session". This can be convenient when write return is masked (e.g., json.Encoder.Encode())

func NewWriteCounter

func NewWriteCounter(w io.Writer) *WriteCounter

func (*WriteCounter) Write

func (wc *WriteCounter) Write(p []byte) (count int, err error)
