	io.ReadCloser
	Size int64
}

CountingReadCloser is an io.ReadCloser which counts the read bytes.

func NewCountingReader

func NewCountingReader(r io.Reader) *CountingReadCloser

NewCountingReader returns a CountingReadCloser.

func (*CountingReadCloser) Read

func (cr *CountingReadCloser) Read(p []byte) (n int, err error)

type CountingResponseWriter

type CountingResponseWriter struct {
	http.ResponseWriter
	Code int
	Size int64
}

CountingResponseWriter is a http.ResponseWriter which counts the written bytes, and stores the response's Code.

func NewCountingRW

func NewCountingRW(w http.ResponseWriter) *CountingResponseWriter

NewCountingRW returns a CountingResponseWriter.

func (*CountingResponseWriter) Write

func (rw *CountingResponseWriter) Write(p []byte) (n int, err error)

func (*CountingResponseWriter) WriteHeader

func (rw *CountingResponseWriter) WriteHeader(code int)

WriteHeader implements http.ResponseWriter.WriteHeader, and record the code.
