Types

type CountingResponseWriter

type CountingResponseWriter interface {
	http.ResponseWriter
	Count() int64
	Status() int
}

func NewCountingResponseWriter

func NewCountingResponseWriter(rw http.ResponseWriter) CountingResponseWriter

type WriteFlusher

type WriteFlusher interface {
	io.Writer
	Flush() error
}

func NewWriteAfterReader

func NewWriteAfterReader(r io.Reader, w io.Writer) (io.Reader, WriteFlusher)

Couple r and w so that until r has been drained (before r.Read() has returned some error), all writes to w are sent to a tempfile first. The caller must call Flush() on the returned WriteFlusher to ensure all data is propagated to w.
